fix: convert content-bearing VARCHAR columns to TEXT to prevent Data too long errors

- Changed all description, remark, notes, reject_reason, cancel_reason,
  audit_reason, summary, advice, overall_assessment, config_value fields
  from VARCHAR(255/500/200) to TEXT across ~40 tables
- Added idempotent modifyColumnToText() migrations in DatabaseInitializer
  (~55 ALTER TABLE MODIFY COLUMN calls) for production database sync
- Primary fix: activities.description was the original crash site but
  many other columns had the same truncation risk
