Closes: #8731

Description

This PR adds privacy controls for time related information in AI request context by introducing two user-configurable settings: includeCurrentTime (default: true) and includeTimezone (default: false).

Key implementation details:

• UI: Implemented dependent checkbox pattern in Context Management settings - timezone checkbox is disabled when time inclusion is off
• Backend: Modified getEnvironmentDetails() to conditionally build time section based on settings flags

Design choice: Timezone disabled by default (privacy improvement) while keeping time enabled (maintains AI time-awareness). This balances privacy with functionality.

Test Procedure

Manual testing performed:

1. Settings UI verification:

   • Open Settings → Context Management
   • Verify two new checkboxes appear under diagnostics section
   • Uncheck "Include current time" → verify "Include timezone" becomes disabled
   • Re-check "Include current time" → verify "Include timezone" becomes enabled

2. Context behavior testing:

   • Scenario A (default): Time enabled, timezone disabled

     • Start new chat, check environment details in context
     • ✅ Should see: # Current Time\nCurrent time in ISO 8601 UTC format: [timestamp]
     • ✅ Should NOT see: User time zone: line

   • Scenario B: Both disabled

     • Disable both settings, save, start new chat
     • ✅ Should NOT see # Current Time section at all

   • Scenario C: Both enabled

     • Enable both settings, save, start new chat
     • ✅ Should see full time section with timezone info

I've completed a comprehensive review of this pull request. The implementation adds privacy controls for time and timezone information in AI request context with two new user-configurable settings.

Review Result: ✅ No Issues Found

The code quality is excellent:

• Type definitions are consistent and properly integrated throughout the stack
• Conditional logic correctly implements the cascading dependency (timezone only shown when time is enabled)
• UI implementation uses a good dependent checkbox pattern
• All translation files include the new settings
• Test fixtures have been properly updated with correct default values
• State management follows existing patterns
