Update default models and pricing across presets

Bump default model names project-wide: gpt-5.4 -> gpt-5.5,
gemini-3.x -> gemini-3.5-flash, glm-5 -> glm-5.1, and
grok-code-fast-1 -> grok-build-0.1 across all provider presets
(claude, codex, gemini, hermes, openclaw, opencode, universal),
Gemini config, and stream check defaults.

Pricing:
- Seed gemini-3.5-flash, gemini-3.1-flash-lite, step-3.5-flash-2603,
  doubao-seed-2.0-code, mimo-v2.5(/pro), qwen3-coder-480b, grok-build-0.1.
- Correct deepseek-v4-flash/pro, glm-5/5.1, grok pricing.
- Add repair_current_model_pricing: idempotent pass that fixes only
  rows still equal to the outdated built-in values, preserving any
  user-customized prices (seed uses INSERT OR IGNORE and cannot update
  existing rows).

Fixes from review:
- opencode: drop duplicate gemini-3.5-flash variant (unreachable via
  .find), keep the entry with the full minimal/low/medium/high set.
- Align stale display names/costs to gemini-3.5-flash (hermes, openclaw,
  opencode); openclaw cost -> {1.5, 9, 0.15} to match seed.
- i18n (zh/en/ja/zh-TW): refresh OMO category tooltips for new model
  names; fix writing tooltip to Kimi K2.5 to match its recommended.

Update tests accordingly and add a regression test asserting unique
model ids in the Google opencode preset variants.
