feat: migrate static data to SQLite and persist runtime timers/events across restarts

[FaiThiX]

Summary

This PR replaces large runtime-loaded JSON static files with SQLite and adds persistent runtime state for timers/event timestamps so data survives bot restarts.

Motivation

Large JSON files in src/staticFiles/ caused high memory usage because they were loaded into heap at runtime.
Additionally, timer/event state (e.g. DeepSea/Cargo/custom timers) was lost or reset incorrectly after restart.

Changes

• Migrated static data storage from JSON files to a single SQLite database (staticData.sqlite).
• Added/updated a manual build script to populate the DB from source JSON files (scripts/buildStaticFilesDb.js).
• Moved raw static source files into a separate gitignored directory (no longer shipped in repo by default).
• Added runtime persistence storage (runtimeData.sqlite) for server-scoped runtime state.
• Persisted/restored:
• custom in-game timers (timer add)
• DeepSea timestamps/state
• Cargo egress timers/state
• Oil rig unlock timers
• additional map-marker related event timestamps
• Fixed restore timing by restoring persistent runtime state during first polling initialization.
• Fixed DeepSea restart reset edge case by deriving active state from current marker set instead of fragile new/left marker transitions.
• Improved Cargo restore robustness by restoring via ID and position fallback, including onItsWayOut state.

Result

• Significant memory reduction after static JSON -> SQLite migration.
• Runtime timers/events now survive bot restart and continue with correct remaining time.
• Removed “temporary wrong initial time” after reconnect/first update for DeepSea/Cargo.

Breaking / Operational Notes

• Raw static JSON files are no longer expected to be versioned/shipped in normal runtime.
• Provide staticData.sqlite in deployment, or run the build script manually to generate it.
• Existing users should verify DB paths and deployment includes the SQLite files.

Validation

• Typecheck/tests passed (npm test -- --pretty false).
• Manual restart tests for DeepSea, Cargo, OilRig unlock timers, and custom timers confirm persistence behavior.
