Louis King c029eae524 feat: persist path_hash_bytes column and add packet list filter
Persist the path-hash byte width (1/2/3) as a nullable Integer column on
RawPacket, computed at ingest by the collector and backfilled for historical
rows via a self-contained Python migration. Replace the per-request Python
decode loop in the grouped-list route with a SQL MAX() aggregate + HAVING
filter, and add a discrete <select> filter (Any/1B/2B/3B) to the /packets
SPA page.

- Model: add path_hash_bytes column to RawPacket (nullable Integer)
- Migration: batch_alter_table add_column + keyset-paginated Python backfill
  reading decoded via Core select() on sa.JSON column (portable across
  SQLite and Postgres)
- Collector: compute path_hash_bytes at ingest via two-tier path-hash
  extraction (decoded.path -> payload.decoded.pathHashes)
- API: add func.max() aggregate to group query, HAVING filter on
  ?path_hash_bytes=1|2|3 param; delete Phase 3 decode loop and dead helper
- Frontend: add path-width select filter wired through query/apiParams/
  pagination/headerParams; add i18n keys (en/nl)
- Tests: 1186 passed, 22 skipped; collector + API + model coverage
