feat(10-03): implement DoeOpenDataAdapter — fetch, extract, D-02 filter

- Native fetch + AbortController 15s timeout (icon-discovery idiom, no
  axios); URL host hardcoded, only the internally-computed dayCursor is
  interpolated (T-10-06)
- HTTP 400 treated as an expected no-op (pubDay today/future) -> []
- adm-zip extraction with a pre-extraction decompression-bomb ceiling
  check (sum entry.header.size vs ~50MB) before any entry buffer is read
  (T-10-07); entries are never written to disk
- D-02 open-tender filter: positive tag.includes('tender') match only —
  award/planning/untagged-with-awards excluded (Pitfall C)
- Register DoeOpenDataAdapter in TendersModule.providers
- All doe-opendata.adapter.spec.ts tests green (6/6)
