New format: single-letter prefix + year + 5-digit sequence.
No direction code (IN/OUT) in the number — shown via arrow icon.
Sequence is shared across directions within the same company+year.
Changes:
- REGISTRY_COMPANY_PREFIX: BTG→B, USW→U, SDT→S, GRP→G
- OLD_COMPANY_PREFIX map for backward compat with existing entries
- allocateSequenceNumber: searches both old and new format entries
to find the actual max sequence (backward compat)
- recalculateSequence: same dual-format search
- parseRegistryNumber: supports 3 formats (current, v1, legacy)
- isNewFormat: updated regex for B-2026-00001
- CompactNumber: already used single-letter badges, just updated comment
- debug-sequences endpoint: updated for new format
- Notification test data: updated to new format
- RegistrySequence.type: now "SEQ" (shared) instead of "IN"/"OUT"
After deploy: POST /api/registratura/debug-sequences to clean up
old counters, then recreate test entries.
