Fix broken menu bar items after facebook.com/messages migration

Update DOM selectors to use aria-label attributes instead of fragile
auto-generated class names that changed with the migration:

- Insert GIF: [aria-label="Choose a GIF"]
- Insert Sticker: [aria-label="Choose a sticker"]
- Insert Emoji: [aria-label="Choose an emoji"]
- Attach Files: [aria-label="Attach a file up to 25 MB"]
- Find Conversation: [aria-label="Search Messenger"] (was selecting Facebook search)
- Search in Conversation: Simplified to click [aria-label="Search"] directly

Fixes issues introduced in commit 5d4e29c
