feat: rename GOD role to IMPLEMENTOR and equalize CODER/IMPLEMENTOR abilities

The GOD role name was confusing — in MUD terminology "god" means any
immortal, not a specific rank. Renamed to IMPLEMENTOR throughout the
codebase. CODER and IMPLEMENTOR now have functionally equivalent
abilities, so most permission checks use CODER as the minimum role.

Also includes: deployments module, equipment set fixes, validation
service updates, mob reset service, zone editor improvements, landing
page redesign, and removal of obsolete Docker/Synology deployment docs.
