Frontend for the credential-set feature, matching the blocklist/house modal
style. Functional end to end against the existing endpoints; visuals are a
clean first pass to refine.
Admin manager (Settings → Connected Accounts, admin-only — empty for non-admins):
per service, the saved accounts render as pills with a delete ✕, and "+ Add
account" reveals an inline form built from each service's required fields.
Create POSTs /api/credentials; secrets are entered but never read back (the API
only returns id/label). Loads via loadCredentialSets() at the end of
loadSettingsData().
Quick-switch modal (sidebar Service Status is now clickable for ALL profiles):
shows, per service the admin set up, a "Default" pill + one pill per account,
highlighting the profile's current choice; clicking persists via
/api/profiles/me/services/select and re-renders. Empty-state message when the
admin hasn't configured any alternates.
webui/static/credential-sets.js (new, registered in index.html), house-style
CSS appended, sidebar made clickable, settings hook added. Registered the new
module in the script-split integrity test (onclick coverage). 64 integrity
tests pass; real-app smoke confirms index renders, the asset serves, and
admin-create → per-profile-list round-trips.
Note: selections are stored but not yet consumed by the live clients (the
resolver remains dormant) — wiring playlist-pull/enrichment to use a profile's
selected account is the next step.
