webui: expose the quality-critical options existing groups were missing

[CryptVenture]

Split out of #374 as requested: options missing from groups that already exist. The new analysis groups, the new TTS groups, the dead controls, the default overrides and the range fixes are separate PRs.

The problem

Twenty groups existed but left out options their families read — including the ones that decide output quality. They were reachable only by hand-writing JSON into the fallback box.

What is added

Group	Options	Read at
omnivoice	t_shift, class_temperature, position_temperature, layer_penalty_factor, denoise, preprocess_prompt, postprocess_output, audio/text chunking	session.cpp:100-116, loader.cpp:34
irodori_tts	seven guidance knobs, duration bounds, no_ref, trim_tail, instruction	session.cpp:451-454 and the guidance block
index_tts2	the whole sampling block — do_sample, temperature, top_p, top_k, repetition_penalty, num_beams, length_penalty	index_tts2/request.cpp
chatterbox	min_p (its actual truncation filter), top_p, s3gen_cfg_rate	chatterbox/session.cpp
qwen3_tts	the sub-talker block, x_vector_only_mode	qwen3_tts/session.cpp:58
minimax_music3	ensemble takes, flow uncond/hop controls	minimax_music3/session.cpp, pipeline.cpp
seed_vc	f0_condition, auto_f0_adjust, semitone_shift	seed_vc/session.cpp — without these the SVC entry cannot do what SVC is for
voxcpm1, voxcpm2, heartmula, neutts, vibevoice, stable_audio, ace_step, minimax_h3, the four firered-audio groups	retry/chunking/sampling/negative-prompt options each family reads	their own sources

What is deliberately left out

The original change also added reference_max_seconds and reference_pad_ms to omnivoice. Nothing in the tree reads either name — src/models/omnivoice reads denoise, duration, guidance_scale, num_inference_steps, preprocess_prompt, postprocess_output, seed, speed, t_shift and the prefixed session options — so they are not here.

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 added control name was checked against its family's sources, or against the shared chunking helpers in src/framework/text/chunking.cpp and src/framework/audio/chunking.cpp.

Scope

One data file, 65 controls added. The 20 deletions in the diff are the previous last line of each group gaining a trailing comma. No code change. The generated bundle is deliberately excluded — it 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.
