feat(pixiv): ledger models + migration 0076 + PixivIngester adapter (#129 step 3)

pixiv_seen_media / pixiv_failed_media mirror the Patreon/SubscribeStar ledgers (keys are always synthesized <illust_id>:p<num> / <illust_id>:ugoira — pximg URLs carry no content hash). PixivIngester wires client/downloader/ ledgers into ingest_core with drift label 'Pixiv app API' and the new body_canary=False opt-out: caption-less pixiv artists are common, so the zero-bodies #862 alarm would false-positive here — the client's response-shape drift checks cover that failure class instead. auth_token joins the uniform adapter constructor (pixiv is the first token-auth native platform). verify_pixiv_credential = one OAuth refresh, no feed walk.

+"""pixiv_seen_media + pixiv_failed_media: per-source ledgers

+
+Pixiv native ingester (milestone #129, gallery-dl → native-core migration).
+Mirrors the Patreon (0037/0038) and SubscribeStar (0054) ledger tables: a
+seen-ledger so routine walks skip already-ingested media (recovery bypasses
+it) and a dead-letter ledger so persistently-failing media stops re-burning
+backfill chunks. Pixiv URLs carry no content hash, so `filehash` is always the
+synthesized ``<illust_id>:p<num>`` / ``<illust_id>:ugoira`` key — String(128)
+matches the siblings. UNIQUE (source_id, filehash) is the upsert key on each.
