ParenScript player.lisp fixes (from easilok):
- Replace == with = for JavaScript equality
- Replace inner-html with inner-h-t-m-l
- Replace parseInt with parse-int
- Replace let with let* where needed for sequential bindings
- Replace new "FormData" with new -Form-data
- Fix audio event listener chaining
- Replace Promise chains with setTimeout callbacks
playlist-management.lisp:
- Remove track-ids field (column doesn't exist, using junction table)
- Update USERS table schema to use TIMESTAMP instead of integer
- Add migration 003 to convert existing integer timestamps to TIMESTAMP
- Remove timestamp-to-unix calls in playlist-management.lisp (use DB default)
- Update user-management.lisp to use postmodern:execute for last-login update
- All timestamp columns now consistently use PostgreSQL TIMESTAMP type
- Fixed field name mismatch: schema uses 'track-ids' not 'tracks'
- Handle Radiance DB storing text fields as lists
- Parse/format comma-separated track IDs properly
- Code is now correct but db:update still doesn't persist (i-lambdalite limitation)
- Requires PostgreSQL for full functionality
