fix: files with non-latin characters fails to open

[Rohit3523]

Proposed changes

Files shared in E2E channels with non-ASCII filenames (like 測試123.txt or Cyrillic characters) were failing to open on both Android and iOS.

This was happening because filenames were not properly decoded during decryption, so URL-encoded values were used instead of the actual names.

🚥 Pre-merge checks | ✅ 4 | ❌ 1

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The PR title mentions 'non-latin characters' but the actual changes only update a dependency commit reference and reformat tsconfig.json comments—neither addresses filename decoding or E2EE file opening issues.	Update the title to reflect the actual changes, such as 'deps: update @rocket.chat/mobile-crypto to specific commit' or clarify if this is an incomplete PR lacking the main implementation.

✅ Passed checks (4 passed)

Check name	Status	Explanation
Linked Issues check	✅ Passed	The code changes update the mobile-crypto dependency to a specific commit, which appears intended to fix filename decoding for Cyrillic characters in E2EE file attachments as required by SUP-1007.
Out of Scope Changes check	✅ Passed	The tsconfig.json changes are formatting-only adjustments with no functional impact. The package.json dependency update is directly related to fixing the Cyrillic filename issue.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}
