fix: jump to quoted message in search and content filter

[Narasimha-sc]

Summary

• Fix tapping a quoted message during search or content filter — previously silently did nothing when the quoted message wasn't in loaded items
• Load around the target without search/filter params using openAroundItemId, which closes search/filter and positions at the target
• Fixes the overly broad guard added in 219381f (android, desktop: don't load new messages when pressing quote while searching #5315)

Test plan

• Search for a message, tap a quoted message in the search results — should close search and navigate to the quoted message
• Activate content filter (e.g., images), tap a quoted message — should close filter and navigate to the quoted message
• Verify normal quote navigation (outside search/filter) still works
