Change cooldown unit from seconds to minutes

- Updated minTimeBetweenTrades config to use minutes instead of seconds
- Changed default from 600 seconds to 10 minutes
- Updated Settings UI label from 'seconds' to 'minutes' and adjusted range (0-60 min)
- Updated .env comments to reflect new unit
- No functional change since cooldown enforcement not yet implemented (TODO in check-risk route)
