webui: add parameter groups for the ASR, VAD, diarization and alignment models

[CryptVenture]

Split out of #374 as requested: missing parameter groups, analysis families. The TTS and music groups, the controls added to existing groups, the dead controls, the default overrides and the range fixes are separate PRs.

The problem

Fourteen ASR, VAD, diarization and forced-alignment families had no group at all in model_params.json, so their entire option surface was reachable only by hand-writing JSON into the fallback box. That includes silero_vad's threshold and min-speech/min-silence knobs — which are the point of that model — and kroko_asr's beam search and hotword biasing.

The change

Groups added: fun_asr_nano, granite5asr, higgs_audio_stt, hviske_asr, kroko_asr, marblenet_vad, nemotron_asr, parakeet_tdt, qwen3_asr, qwen3_forced_aligner, silero_vad, sortformer_diar, vibevoice_asr, voxtral_realtime — 57 controls in total.

Every control is named after the key its family's session actually reads. The shared audio_chunk_mode and audio_chunk_duration_sec controls are read through src/framework/audio/chunking.cpp:167 and :190, which each of these families calls; the rest resolve inside the family's own sources.

No existing group is touched, so nothing that worked before changes.

Validation

python3 -m json.tool webui/configs/model_params.json   # parses
python3 tools/check_loader_catalog_sync.py
# ok: runtime loaders, model_specs, and model_manager_v2 are in sync

Every one of the 57 control names was checked against its family's sources — either a literal "<name>" in the family directory, or the shared chunking helper above.

Scope

One data file, 85 added lines, no deletions. No code change. The generated bundle is deliberately excluded — catalog.ts inlines this file at frontend build time and the bundle is not byte-reproducible, so regenerating it in each PR of this split would make the PRs conflict; happy to send one bundle-regeneration PR once the series lands.

Closing for now to stay inside the 3-concurrent-PR policy (see the discussion on #422). Nothing is wrong with the change and CI is green on it; I will reopen it as review slots free.
