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.

Critical bug: ADIF parser was only parsing 1 QSO from multi-MB LoTW reports.
Root cause: The regex.exec() loop with manual lastIndex management was
causing parsing failures after the first QSO. The while loop approach with
regex state management was error-prone.
Fix: Replaced regex.exec() while loop with matchAll() for-of iteration.
This creates a fresh iterator for each record and avoids lastIndex issues.
Before: 6.8MB LoTW report → 1 QSO parsed
After: 6.8MB LoTW report → All QSOs parsed
The matchAll() approach is cleaner and more reliable for parsing ADIF
records with multiple fields.

- Add shared ADIF parser utility (src/backend/utils/adif-parser.js)
- parseADIF(): Parse ADIF format into QSO records
- parseDCLResponse(): Parse DCL's JSON response format
- normalizeBand() and normalizeMode(): Standardize band/mode names
- Implement DCL service (src/backend/services/dcl.service.js)
- fetchQSOsFromDCL(): Fetch from DCL API (ready for API availability)
- parseDCLJSONResponse(): Parse example payload format
- syncQSOs(): Update existing QSOs with DCL confirmations
- Support DCL-specific fields: DCL_QSL_RCVD, DCL_QSLRDATE, DARC_DOK, MY_DARC_DOK
- Refactor LoTW service to use shared ADIF parser
- Remove duplicate parseADIF, normalizeBand, normalizeMode functions
- Import from shared utility for consistency
- Tested with example DCL payload
- Successfully parses all 6 QSOs
- Correctly extracts DCL confirmation data
- Handles ADIF format with <EOR> delimiters
