Fase 16.2 + 16.3 — replace the bare `m.loading()` text at every
pre-existing async-loading site with `<Spinner size=...> + <span>`.
Text is kept (visual fallback + tooltip / SR redundancy). No new
loading semantics — only existing flags get a visual indicator.
Sites:
- (app)/+layout.svelte: auth splash gets `size="lg"` centred under the
loading label.
- (app)/search/+page.svelte: inline `size="sm"` next to the search-in-flight
copy.
- (app)/notes/archive/+page.svelte: inline `size="sm"` next to the
archive-load copy.
- lib/components/CreateCollectiveModal.svelte: inline `size="sm"` inside
the disabled Save button while the create RPC is in flight.
- (app)/collective/manage/+page.svelte: three sites — members-list load,
invitation-generate button, and add-common-item Save button.
E2E (tests/e2e/spinner.test.ts):
- SP-E-01 throttles search_in_collective RPC by 500ms and asserts the
spinner is visible in the loading paragraph.
- SP-E-02 throttles set_item_frequency_weight RPC and asserts the spinner
is scoped inside the Save button.
- SP-E-03 seeds an expired `sb-192-auth-token` so GoTrue is forced to
call /auth/v1/token, then hangs that endpoint indefinitely and
asserts the splash spinner is visible. Storage key derivation matches
Supabase's `sb-${hostname.split('.')[0]}-auth-token` default; we
populate both the LAN-IP variant and a loopback fallback for
resilience.
