Merge branch 'main' into feat/trace-details-pending

* fix(authtypes): embed values and expose AuthDomainConfig oneOf

GettableAuthDomain now embeds StorableAuthDomain and AuthDomainConfig
by value so the response flattens correctly. AuthDomainConfig also
implements jsonschema.OneOfExposer over the SAML/Google/OIDC variants.

* fix(alertmanagertypes): expose PostableChannel JSONSchema

PostableChannel now implements jsonschema.Exposer, requiring name
and a oneOf branch per *_configs field so the OpenAPI request body
for POST /channels matches the runtime contract enforced in
NewChannelFromReceiver. Switched the route's Request type from
Receiver to PostableChannel and regenerated the OpenAPI spec.

* fix(alertmanagertypes): use components/schemas prefix in PostableChannel refs

The standalone reflector inside JSONSchema defaulted to #/definitions/
prefix, producing dangling refs to ConfigDiscordConfig etc. that broke
the generated frontend client. Pass DefinitionsPrefix("#/components/schemas/")
so refs point to existing OpenAPI components, and regenerate the frontend
Orval client.

* feat(authdomain): add GET /api/v1/domains/{id} endpoint

Returns a single GettableAuthDomain scoped to the caller's organization,
backed by the existing module.GetByOrgIDAndID. Adds Get to the Handler
interface, wires the route under AdminAccess, and regenerates the
OpenAPI spec and frontend Orval client.

* feat(authtypes): expose AuthNProvider enum in OpenAPI schema

AuthNProvider now implements jsonschema.Enum, narrowing the generated
TypeScript type from string to a typed enum. Updated callers in the
auth-domain settings UI and mocks to use AuthtypesAuthNProviderDTO,
and added an early-return guard in the create/edit submit handler so
TS can narrow the union before passing it as ssoType.

* chore(types): document oneOf/discriminator mismatch on PostableChannel and AuthDomainConfig

Both types emit a oneOf in the OpenAPI spec but neither shape supports an
OpenAPI discriminator: PostableChannel implies the variant by which *_configs
field is present, and AuthDomainConfig keeps the variant payload in a
sibling field instead of being the payload itself. Leave a TODO pointing at
ruletypes.RuleThresholdData as the envelope pattern to migrate to.

* fix(ruletypes): handle string driver values in Schedule.Scan and Recurrence.Scan

The Scan methods only handled []byte and silently no-op'd on anything
else. SQLite's TEXT columns come back as string from the driver, so
every GET of a planned_maintenance returned a zero-valued Schedule
(empty timezone, 0001-01-01 startTime/endTime, no recurrence) — even
though Create + Update wrote the values correctly.

Switch on src type, accept []byte, string, and nil; error on anything
else. Aligns Schedule with the existing pattern; in Recurrence fixes
the receiver — Unmarshal was being passed src (the interface{} arg)
rather than r.
