fix(mobile): render DrawerPortal inside BottomSheetModalProvider so comment kebab opens

[dylanjeffers]

Summary

The kebab overflow menu on a comment in the mobile Comment Drawer wasn't opening — tapping it did nothing. This is a follow-up to #14385 which removed a redundant CommentSectionProvider wrap but didn't actually fix the user-facing bug.

Root cause

@gorhom/bottom-sheet's BottomSheetModalProvider wraps its children in its own nested <PortalProvider rootHostName='bottom-sheet-portal-XXX'> with an isolated host registry. @gorhom/portal resolves a Portal's hostName against the nearest PortalProvider only — it does not walk up to outer providers.

With the DrawerPortal host registered as a sibling of BottomSheetModalProvider, any <Portal hostName='DrawerPortal'> rendered from inside a bottom sheet (the kebab on a comment row, or the track-owner overflow in CommentDrawerHeader) resolved through the inner provider, found no DrawerPortal host, and silently rendered nowhere. onPress fired, state updated, but the action drawer never appeared.

Fix

Move <PortalHost name='DrawerPortal' /> from outside BottomSheetModalProvider to inside it (alongside ChatReactionsPortal). Now it's registered in the same registry the inner Portals look up. External callers (e.g. ContestCommentsList outside any bottom sheet) still find it through the same provider chain because there's only one PortalProvider between them and the host.

Test plan

• Tap kebab on a comment in the mobile Comment Drawer → action drawer appears with Share / Mute Thread / Edit / Delete
• Tap kebab on another user's comment → drawer appears with Flag, Mute User, etc.
• Tap a row in the action drawer → drawer closes, action runs
• Tap backdrop to dismiss the action drawer; tap kebab again → drawer reopens on first tap
• Verify ContestCommentsList kebab still works (caller outside any bottom sheet)
• Track-owner kebab in CommentDrawerHeader still works (same DrawerPortal host)
