feat(provider/vllm_rerank): add configurable rerank_api_suffix option (#7278)

* feat(provider/vllm_rerank): add configurable rerank_api_suffix option

Add rerank_api_suffix config option to the VLLM Rerank provider so
users can control the API URL path suffix instead of having /v1/rerank
hardcoded.

- Default value is /v1/rerank (preserves existing behavior)
- Users can set it to empty string to disable auto-append
- Handles suffix without leading slash by auto-adding one
- Schema, default config, and i18n metadata all updated

Issue: Fixes #7238

* fix(provider/vllm_rerank): handle null suffix and improve hint descriptions

- Add explicit None check for rerank_api_suffix (fixes HIGH from Gemini)
- Update rerank_api_base hint to describe actual behavior without
  mentioning specific provider options (fixes 3x MEDIUM from Gemini)
- Add ru-RU i18n for rerank_api_suffix (fixes P2 from Codex)
