Pull request overview

This PR merges changes from stage into main, primarily updating exercise behavior across the backend (DB + services + tests) and frontend (table + dialog) while improving search indexing correctness.

Changes:

• Make exercises.name case-insensitive at the DB level (Postgres CITEXT) and update conflict tests accordingly.
• Adjust exercise querying/ordering and ensure updated_at changes when only muscle groups are modified.
• Add “view” mode for system exercises in the client and extend the shared DataTable column meta to support responsive header/cell classes; ensure Meilisearch settings updates complete before document indexing.
