fix(db): provision CV builder + AI workspace tables via the MySQL-safe reconciler
Deploy failed on prod (MariaDB) while the test job was green: backend startup threw during Database.Migrate(), so deploy.sh's post-deploy health check exited. Root cause: AddCvVariants/AddAiInteractions were scaffolded against SQLite, so they bake SQLite type names into their DDL — DateTimeOffset emits `TEXT`, bool/int emit `INTEGER`, and the PK gets no AUTO_INCREMENT. Run against MariaDB that yields a structurally wrong table, and the composite index over a TEXT column then trips "ERROR 1071: Specified key was too long; max key length is 3072 bytes". SQLite accepts all of it, which is why local/container verification passed. Fix, following the pattern already used for CareerProfiles/AiWorkspaceNotes: - both migrations become no-ops; the three tables are reconciler-owned - reconciler provisions them idempotently per dialect (MySQL: varchar/int AUTO_INCREMENT/datetime(6); SQLite: CREATE TABLE IF NOT EXISTS) - DropMalformedMySqlTable rebuilds a half-built table left by the failed migration, guarded on row count so a table with ANY rows is never dropped - bound the indexed string columns with HasMaxLength so the model matches Verified against a real MariaDB 11 container: reproduced error 1071, then confirmed the corrected DDL yields auto_increment PKs, varchar/datetime columns and all previously-failing indexes. 306 backend tests green; SQLite container starts clean.
