fix: improve check-in reliability, decompression handling, and input parsing

[ismlEraslan]

Summary of Changes

This PR resolves issues with failed check-ins, fixes response decompression handling, and adds safeguards for common user configuration issues:

1. Fix Response Decompression in Node.js:

   • Removed manual �ccept-encoding: gzip, deflate, br, zstd and connection: keep-alive headers.
   • Forcing zstd can cause Cloudflare/HoYoLAB to return zstd-compressed responses that Node.js native etch (undici) does not automatically decompress, resulting in
     es.json() decompression/parse errors. Removing manual encoding headers lets Node's native fetch negotiate supported encodings (gzip, deflate, �r) seamlessly.

2. Secret & Variable Fallbacks in Actions Workflow:

   • Updated login.yml so that COOKIE, GAMES, and HOYOLAB_LANG accept values from either GitHub Actions secrets or �ars (e.g. ${{ secrets.COOKIE || vars.COOKIE }}). This prevents crashes when users configure GAMES as a Secret or COOKIE as a Variable.

3. Schedule Right After Daily Reset:

   • HoYoLAB daily check-in resets at 00:00 UTC+8 (16:00 UTC). Added a scheduled run at 16:30 UTC (00:30 UTC+8) shortly after reset, while keeping 22:15 UTC (06:15 UTC+8) as a morning backup check.

4. Input Sanitization & Game Aliases:

   • Strips accidental surrounding quotes and whitespace from cookies and game lists.
   • Splits game inputs by commas or spaces (gi, hsr or gi hsr).
   • Added common aliases (e.g. genshin -> gi, starrail -> hsr, zenless -> zzz).

5. Enhanced Error Messages:

   • Added friendly handling for
     etcode: 1034 (Risk system / CAPTCHA verification required), advising users to check in manually once on the site/app to clear verification.
   • Displays HoYoLAB's actual json.message in error logs instead of generic messages.
