transcode: clean up unused parameters and fix SonarQube issues

- Removed unused `opts` parameter from _video_filters_get_filters() and tvh_video_context_open_filters().
- Updated all call sites accordingly.
- Split combined variable declaration for clarity.
- Marked AVFilterLink pointer as const to reflect read-only use.

No functional changes — purely code hygiene fallout linked to PR #1859
