Clients cannot discover the named voices that an installed TTS model accepts without consulting backend-specific documentation. Expose voice metadata through the audio API and let custom model configs declare their own catalog. Assisted-by: Codex:gpt-5

Description
Adds
GET /v1/audio/voicesand/audio/voicesso clients can discover named voices for installed TTS models. The optionalmodelquery filters the response. The endpoint respects per-user model allowlists and resolves aliases.Model configs can declare
tts.voicesentries with name, language, and gender metadata. Pocket TTS receives a built-in catalog, including pinned backend variants. The change also updates route discovery, API instructions, Swagger, authorization, configuration metadata, tests, and TTS documentation.Closes #11604
Verification
go test ./core/config -ginkgo.focus='TTSVoicesForModel'go test ./core/http/endpoints/localai -ginkgo.focus='TTSVoicesEndpoint'go test ./core/config/meta ./core/http/authgo test ./core/http/routes -run '^$'jq -e '.paths["/v1/audio/voices"].get.responses["200"]' swagger/swagger.jsongit diff --checkThe full routes suite was not run because one existing spec requires a rootless Docker/Postgres provider that is unavailable in this worktree.
Notes for Reviewers
The endpoint returns only models with known voice metadata when unfiltered. A filtered installed model without metadata returns an empty
voiceslist.Signed commits
