refactor: remove artificial timeouts from bookmark decryption

Removed all withTimeout wrappers - now matches debug page behavior:
- Direct decrypt calls with no artificial timeouts
- Let operations fail naturally and quickly
- Bunker responds instantly (success or rejection)

No timeouts needed because:
1. Account queue is disabled (requests sent immediately)
2. Only decrypting truly encrypted content (no wasted attempts)
3. Bunker either succeeds quickly or fails quickly

This makes bookmark decryption instant, just like the debug page
encryption/decryption tests.
