feat(ingestion): Mark entities dirty on ingest for document regeneration

Integrates the dirty tracking system into all four ingestion paths
(issues, MRs, issue discussions, MR discussions). After each entity
is upserted within its transaction, a corresponding dirty_queue entry
is inserted so the document regenerator knows which documents need
rebuilding.

This ensures that document generation stays transactionally consistent
with data changes: if the ingest transaction rolls back, the dirty
marker rolls back too, preventing stale document regeneration attempts.

Also updates GiError references to LoreError in these files as part
of the codebase-wide rename, and adjusts issue discussion logging
from info to debug level to reduce noise during normal sync runs.
