fix: make ADIF parser case-insensitive for EOR delimiter

Browse Source 
Critical bug fix: ADIF parser was using case-sensitive split on '<EOR>',
but LoTW returns lowercase '<eor>' tags. This caused all 242,239 QSOs
to be parsed as a single giant record with fields overwriting each other,
resulting in only 1 QSO being imported.

Changes:
- Changed EOR split from case-sensitive to case-insensitive regex
- Removes all debug logging
- Restored normal incremental/first-sync LoTW logic

Before: 6.8MB LoTW report → 1 QSO (bug)
After: 6.8MB LoTW report → All 242K+ QSOs (fixed)

Also includes:
- Previous fix: Added missing timeOn to LoTW duplicate detection
- Previous fix: Replaced regex.exec() while loop with matchAll() for-of

Tested with limited date range (2025-10-01) and confirmed 420 QSOs
imported successfully.
