🦉 feat: Claude Opus 4.7 Model Support (#12698)

* 🦉 feat: Claude Opus 4.7 Model Support

- Add `claude-opus-4-7` to shared Anthropic models and `anthropic.claude-opus-4-7` to Bedrock models
- Register 1M context window and 128K max output in anthropic token maps
- Add token pricing ($5/$25), cache rates (6.25/0.5), and premium tier ($10/$37.50 above 200K) in tx.ts
- Update `.env.example` with Opus 4.7 IDs in `ANTHROPIC_MODELS` and `BEDROCK_AWS_MODELS` examples
- Add parallel Opus 4.7 test cases for token/cache/premium rates, context length, max output, name-variation matching, and 1M-context qualification

* feat: Add `xhigh` Effort Level for Opus 4.7

- Add `xhigh` variant to `AnthropicEffort` enum between `high` and `max`
- Expose `xhigh` in `anthropicSettings.effort.options` and the UI slider `enumMappings`
- Reuse existing `com_ui_xhigh` translation key

* test: Cover `xhigh` Effort and Exact Opus 4.7 Premium Rates

- Assert `xhigh` position (between high and max), inclusion in
  `anthropicSettings.effort.options`, zod acceptance, and rejection of
  unknown values in schemas.spec.ts
- Verify bedrockInputParser emits `output_config: { effort: 'xhigh' }`
  for adaptive `anthropic.claude-opus-4-7`
- Verify getLLMConfig sets adaptive thinking and `output_config.effort =
  'xhigh'` for `claude-opus-4-7`
- Pin Opus 4.7 premium pricing to exact threshold/prompt/completion
  values (200000 / 10 / 37.5) so silent rate drift fails the test
