Refactor event and session column names to camelCase

- Updated test cases to reflect new column names (eve_MAC -> eveMac, eve_DateTime -> eveDateTime, etc.) across various test files.
- Modified SQL table definitions in the database cleanup and migration tests to use camelCase naming conventions.
- Implemented migration tests to ensure legacy column names are correctly renamed to camelCase equivalents.
- Ensured that existing data is preserved during the migration process and that views referencing old column names are dropped before renaming.
- Verified that the migration function is idempotent, allowing for safe re-execution without data loss.
