fix(scripts): update run.sh to use mev-beta binary and set PROVIDER_CONFIG_PATH

- Fixed binary name from mev-bot to mev-beta (line 82)
- Added automatic PROVIDER_CONFIG_PATH export (defaults to config/providers_runtime.yaml)
- Created .env.production template with all required variables
- Added provider config path display in startup messages

This ensures the bot uses the correct binary and provider configuration
when started with scripts/run.sh
