fix: added default value in useUserPreferences

[Rohit3523]

Proposed changes

The useUserPreferences hook expects both a key and a default value, but during the migration from react-native-mmkv-storage to react-native-mmkv, we forgot to add the default value for the accessibility setting. Because of this missing default value, the switch stopped working and did not reflect state changes.

Introduced in #6744

Summary by CodeRabbit

• Bug Fixes

  • Standardized default behavior for mentions and room hashtags so prefixes ('@' / '#') are now disabled by default when no preference is set.

• Bug Fixes

  • Restored consistent default for GIF autoplay so animated images start playing by default when no preference is set.

Walkthrough

Added explicit default values to several useUserPreferences calls: mentions/hashtags and accessibility preferences now default to false, while GIF autoplay defaults to true. No other logic or signature changes.

Changes

Cohort / File(s)	Summary
Mention components app/containers/markdown/components/mentions/AtMention.tsx	useUserPreferences(USER_MENTIONS_PREFERENCES_KEY, false) — added false default for mentionsWithAtSymbol.
Hashtag component app/containers/markdown/components/mentions/Hashtag.tsx	useUserPreferences(ROOM_MENTIONS_PREFERENCES_KEY, false) — added false default for roomsWithHashTagSymbol.
Accessibility & appearance view app/views/AccessibilityAndAppearanceView/index.tsx	Two useUserPreferences calls updated to pass false as the default for USER_MENTIONS_PREFERENCES_KEY and ROOM_MENTIONS_PREFERENCES_KEY.
Image viewer app/containers/ImageViewer/ImageViewer.tsx	useUserPreferences(AUTOPLAY_GIFS_PREFERENCES_KEY, true) — added true default for autoplayGifs/isPlaying.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Uniform pattern change (adding default arg) across small number of files.
• Pay attention to: AtMention.tsx, Hashtag.tsx, index.tsx (Accessibility view), and ImageViewer.tsx to confirm intended defaults and any UI implications.

Poem

🐰 I nibble defaults, small and bright,
false for tags, true for GIF delight,
a hop, a tweak, preferences set,
tiny changes — no regret! 🥕✨

33-33: LGTM! Bugfix correctly adds missing default value.

The default value of true is appropriate for GIF autoplay in a messaging context, ensuring GIFs play automatically unless the user explicitly disables this preference.
