fix(tickets,templates): standardize staff permission checks in templates (#151)

[b3lz3but]

Summary

• Replace inconsistent user.is_staff and user.is_staff or user.staff_role checks with user.is_staff_user across all ticket templates and backend views
• Fixes support agents (staff_role="support", is_staff=False) being locked out of reopen button, internal notes, list view staff features, and attachment access
• Increases comments container max-height from 384px to 600px on both platform and portal to eliminate excessive vertical whitespace

Files changed (8)

File	What
tickets/detail.html	Reopen button check
tickets/partials/comments_list.html	Internal note visibility (2 checks)
tickets/list.html	Header, search, skeleton grids (8 checks)
tickets/partials/tickets_table.html	Customer column, empty state (5 checks)
tickets/partials/status_and_comments.html	Staff reply actions, help text, container height
components/mobile_header.html	Business section nav
tickets/views.py	Internal note permission, comment type, is_public flag, attachment access
Portal status_and_comments.html	Container height fix

Test plan

• Verify support agent (staff_role="support", is_staff=False) can see reopen button on closed tickets
• Verify support agent can see internal notes in comment list
• Verify support agent sees staff features in ticket list (filters, customer column)
• Verify support agent can access internal note attachments
• Verify customer users cannot see internal notes or staff features
• Verify comments container no longer has excessive whitespace below content

Closes #151

Pull request overview

Standardizes “staff” permission checks across ticket templates and ticket backend logic by using the custom user.is_staff_user flag, and adjusts a few unrelated test/CI/security hardening changes included in the PR.

Changes:

• Replace template conditionals (user.is_staff, user.is_staff or user.staff_role) with user.is_staff_user across ticket UI components.
• Update ticket backend permission checks (internal notes + internal attachment access) to rely on user.is_staff_user.
• Misc: improve SES/SNS webhook key-type safety, adjust API security tests to use real HMAC middleware helpers, and tweak CI test discovery invocation.

• These permission checks now depend on user.is_staff_user, but the current User.is_staff_user implementation returns bool(self.staff_role) (it does not include Django’s is_staff). That means users with is_staff=True but an empty staff_role will be treated as non-staff here (can’t create internal notes, comment type becomes customer, internal attachments blocked, etc.). Fix by updating is_staff_user to include is_staff (or adjust these checks to consider user.is_staff as well) so the new standard doesn’t regress existing staff accounts.

    if is_internal and not user.is_staff_user:
        messages.error(request, _("❌ You do not have permission to create internal notes."))
        return redirect("tickets:detail", pk=ticket_pk)
    return None


def _determine_comment_type(user: User, is_internal: bool) -> str:
    """Determine the appropriate comment type based on user permissions."""
    if is_internal and user.is_staff_user:
        return "internal"
    elif user.staff_role in ["support", "admin", "manager"]:
        return "support"
    else:
        return "customer"

Re-review: REWORK — 3 blocking issues + incomplete standardization

Must fix before merge (blocking)

1. Merge conflict
PR is CONFLICTING with master. Rebase required. Master has recent commits touching webhooks.py (already on master), test_orders_edit.py, and test_api_users_security.py — all included in this PR as unrelated changes that will conflict.

2. HTMX reply path uses `user.is_staff` instead of `user.is_staff_user`
`tickets/views.py:460` — `can_edit = ticket.status != "closed" or user.is_staff` was missed during migration. A support agent (`staff_role="support"`, `is_staff=False`) sees edit controls on page load but loses them after HTMX reply.

3. HTMX reply path sends ALL comments to template (including internal notes)
`tickets/views.py:461-468` — The HTMX response uses `ticket.comments.all()` without the server-side staff filter that `ticket_detail()` and `ticket_comments_htmx()` apply. Internal notes reach the template for all users — the `{% if %}` template check is the only gate. Apply the same queryset filter:
```python
if user.is_staff_user:
comments = ticket.comments.all().order_by("created_at")
else:
comments = ticket.comments.filter(comment_type__in=["customer", "support"]).order_by("created_at")
```

Should fix

4. `_determine_comment_type` elif still uses raw `staff_role` check
`views.py:260` — `user.staff_role in ["support", "admin", "manager"]` excludes `"billing"` role. Should be `user.is_staff_user` for consistency.

5. Template standardization is incomplete
The PR only migrates ticket templates. `base.html:113`, dashboard (16 occurrences), billing templates, and customer templates still use `user.is_staff or user.staff_role`. This creates inconsistent UX — navbar shows staff options but ticket pages don't (or vice versa) for edge-case users. Per project convention ("template fix cascade"), grep ALL template dirs before committing.

6. Unrelated changes bundled
4 of 12 files are unrelated to template permission checks: `webhooks.py` (RSA type narrowing — already on master), `test_api_users_security.py` (HMAC mixin), `test_orders_edit.py` (editable fields), `platform.yml` (CI fix — already on master). These should be split out or at minimum documented in the PR description.

7. `is_staff_user` property definition may need widening
`models.py:151` — Property is `return bool(self.staff_role)` which drops the `is_staff` leg. The old pattern was `is_staff or staff_role`. A user with `is_staff=True, staff_role=""` (created by `setup_test_users.py` and admin panel) loses staff privileges in ticket views. Verify this is intentional, or widen to `return self.is_staff or bool(self.staff_role) or self.is_superuser`. This is also flagged in PR #154 review — the two PRs should be coordinated.

What's good

• Template migration direction is correct — `user.is_staff_user` is the right target
• `comments_list.html` double-gate (view filter + template check) is solid defense-in-depth
• `mobile_header.html` change is clean
• CSS scroll height adjustment is reasonable (verify Tailwind version supports `max-h-150`)

[b3lz3but]

Review feedback addressed

max-h-150 — no change needed. `max-h-150` is a valid Tailwind CSS v4 utility class (150 × 4px = 600px). This project uses Tailwind v4 where the spacing scale generates these classes natively. IDE confirms: "The class max-h-[600px] can be written as max-h-150".
