Polish mobile onboarding and profile setup (#8438)

Originally stacked on #8375, now merged. Rebased onto main.

Polishes the onboarding landing page, community-link entry, and recovery
sheets. Profile setup uses a consistent sheet with a larger avatar,
inline display name, and draft photo/emoji/animated editing; iOS uses
native controls and coordinated avatar/sheet transitions.

Validation: mobile analysis, full tests, and normal pre-push checks
passed after rebase. Prior iOS build and device walkthrough passed;
native validation was not repeated after this rebase. Snapshots omitted
as requested.
