tiennm99 e695d9b223 feat: port logic from Java original to align with current Java behavior
- Switch Telegram parse mode to HTML to match Java client.
- Rename command identifiers to Java's: delgroup/delapple/delgoogle/
  checkappscore/rawappleapp/rawgoogleapp.
- Move admin singleton to "common" collection at _id="admin".
- Store group _id as string-of-int64 to match Java AbstractModel schema.
- Add `class` discriminator field on persisted models.
- Expand AppleAppResponse (42 fields) and GoogleAppResponse (63 fields,
  with nested Category/Feature) to match Java records.
- Add AppleAppRequest (track id or bundle id) / GoogleAppRequest types.
- Implement Raw* commands as Telegram document attachments instead of
  truncated text.
- Group-authorization gate (admin.HasGroup(chatId)) on non-admin commands.
- Cache TTL via millis timestamp; round score to 1 decimal; weekend silent
  send in scheduler.
- Match Java table renderer: " │ " separators, "─┼─" rows every 5 lines.
- Prefer MONGODB_CONNECTION_STRING env (Java parity); auto-extract DB
  name from URI with fallback to "store-scraper-bot".

Note: This is an AI-assisted port (not human-verified). Behavior parity
with the Java implementation has not been tested end-to-end; treat as a
starting point.
