Calendar connections UI: no error/success feedback (stuck loading, silent failures)

[pdovhomilja]

Deferred from the two-way calendar sync work (P4, v0.17.0).

The calendar connections/settings UI swallows failures:

• CalendarConnectionsList fetch calls lack try/catch — a network failure leaves the component stuck on "Loading…" with no error state.
• Disconnect ignores res.ok — a failed disconnect appears to succeed.
• The settings save form has no success/failure feedback.
• Connect links use a plain <a> (minor — verify intended).

Fix

Add error/success states (toast or inline) and handle non-ok responses in the connections list and settings save flow.

Area

Calendar connections list component + admin calendar-settings page.

Hi, I’d like to work on this. I’ll keep the fix scoped to the calendar connections UI feedback/loading state and avoid touching provider sync logic unless required.
