Walkthrough

The changes introduce Qdrant-based similar-case retrieval functionality gated by the vsearch feature. The CasePage struct is extended with case ID and similar cases fields. The case handler gains optional Query parameter support and conditional logic to compute similar cases from Qdrant. A new async similar function queries Qdrant's recommendation API. Template and CSS updated to conditionally display similar cases.

Changes

Cohort / File(s)	Summary
Qdrant Integration & Case Handler src/controller.rs	Adds QueryCase struct and similar async function for Qdrant-backed recommendations. Extends CasePage with id, enable_similar, and similar_cases fields. Enhances case handler to accept optional Query parameter, conditionally fetch similar cases when vsearch enabled and with_similar requested, and populate CasePage with results. New Qdrant imports added.
Template UI templates/case.html	Introduces conditional section rendering similar cases list when enable_similar is true, displaying case IDs and names after main content.
Print Styles static/style.css	Hides .similar-cases element in print view alongside existing hidden elements.

Poem

🐰 A flutter of whiskers, a twitch of my nose,
Similar cases now bloom where the query goes!
Qdrant's swift dance, through the feature gate, so bright,
Templates render them prettily—oh, what a sight! ✨
