chore: improve DX scripts, fix test suite, and harden tooling

Scripts:
- remote.sh: remove unused open_browser() function
- deploy-remote.sh: add DB backup before deploy, --skip-backup flag, step numbering
- db-backup.sh: fix macOS compat (xargs -r is GNU-only), use portable approach
- db-restore.sh: add safety backup before restore, SQL file validation, file size display
- logs.sh: default to no-follow with --tail=100, order-independent arg parsing
- docker-cleanup.sh: add Docker health check, colored output
- test-sequential.sh: exclude *.integration.test.ts by default, add --integration flag
- simulate-ci.sh: pass --integration flag (has real DB)

Tests:
- db.test.ts: fix mock path from ./DrizzleClient to @shared/db/DrizzleClient
- server.settings.test.ts: rewrite mocks for gameSettingsService (old config/saveConfig removed)
- server.test.ts: add missing config.lootdrop and BotClient mocks, complete DrizzleClient chain
- indexes.test.ts: rename to indexes.integration.test.ts (requires live DB)

Config:
- package.json: test script uses sequential runner, add test:ci and db:restore aliases
- deploy.yml: use --integration flag in CI (has Postgres service)
