Refresh personal sidebar groups after successful Outbox Retry without reload #739

Problem

The PR #710 reviewer reports that after an Outbox Retry succeeds, Refresh groups and stars can still show a removed personal section until full reload. The same stale-catalog behavior affects existing personal Move on main; this is not introduced by the removal PR.

Source evidence

At current main bd3897ce884acb925e24c5be9a2f77fc6b74e37d, src/features/relay/sidebar-personal-groups.ts:18-29 refreshes ChannelKit only when its snapshot is not already ready. src/features/relay/session.ts calls this reader from the saved-sidebar-preferences read. PR #710 leaves that reader unchanged. A ready catalog can therefore survive an explicit sidebar refresh after exact-event retry updates relay state.

Reviewer-reported reproduction

1. With personal groups active, cause a personal-group mutation to remain unresolved in Outbox.
2. Restore delivery and Retry the same signed event in Channel settings → Diagnostics → Outbox; verify success.
3. Choose Refresh groups and stars. The old placement/section can remain.
4. Full reload loads the updated groups.

Expected and scope

Explicit refresh should obtain a fresh personal catalog before projecting saved groups, preserving source opt-in, lifecycle fencing, last-good data on failure, and legacy behavior. Do not add automatic publication/replay or duplicate delivery ownership. Cover both existing Move and section removal, with controlled retry completion and an already-ready catalog; refresh failure must not erase confirmed data.
