changePassword now documents that on Navidrome the change also ends the
user's sessions on its other APIs, regardless of revokeOtherGrants, which
only covers API v1 grants.
Adds the seven auth operations to the spec (createAccessToken, listGrants,
revokeGrant and logout in core; login, setupFirstAdmin and changePassword in
the password module), the bearerAuth/grantAuth schemes, and vacuum rules
requiring explicit security and a known x-scope. The strict handlers sit on
core/apiauth and are covered end to end against a real SQLite database.
The first operations with parameters make the generated code import
github.com/oapi-codegen/runtime. An oapi-codegen overlay renames the shared
offset/limit parameter types, since a generated Offset clashes with Ginkgo's
dot-imported Offset in this package's tests; the published spec is unchanged.
