Sample Data Seeding System (Issue #141)

Adds a profile-based sample data seeding system for fresh Observer installs.

What's included

Profile system — JSON-based profiles stored in core/data/profiles/. Adding a new profile like French radio or Digital Signage is just a new folder, no code changes needed.

English Community Radio profile seeds:

• 20 categories
• 291 genres across Music, Images, Video, SFX and PSA Audio
• Users (admin, basic_user, manager) with permission groups
• Client settings and media format settings
• 3 custom metadata fields (Internal Memo, Physical Tags, Day Parting)
• 4 playlists including a Live Assist board
• Sample Player with 8 daily recurring shows

CLI commands

• ob seed list — list available profiles
• ob seed run <profile> — seed a profile

Admin UI — Import Sample Data button in admin panel, no command line needed

Notes

• Fully idempotent, safe to run multiple times, skips existing data
• Tested on local 5.5-develop and verified on sandbox server
• Profile data extracted and mapped from Pyrate 3 reference DB
