Subject: [PATCH] chore: upgrade to 1.7.0+v2.7.5

Confirms immich-server at the latest v2.7.5 + holds the DB pin immich v2.7.5 ships
(14-vectorchord0.4.3-pgvectors0.2.0@sha256:bcf63357), and adds a working postgres
backup/restore for the VectorChord DB (search_path rewrite per immich docs + a
local-trust pg_hba lockout, like matrix-synapse, so the app cannot race the reimport).

+# Postgres backup/restore hook for the immich `database` service (VectorChord/pgvecto.rs image).
+# Invoked by backupbot-two via the deploy labels:
+#   backupbot.backup.pre-hook              = "/pg_backup.sh backup"
+#   backupbot.backup.volumes.postgres.path = "backup.sql"
+#   backupbot.restore.post-hook            = "/pg_backup.sh restore"
+#
+# IMPORTANT — why this restore does NOT drop the database:
+# immich's postgres image bundles the legacy pgvecto.rs (`vectors`) extension. Dropping the immich
+# database (DROP DATABASE) destabilises its background worker, which then recurses on its own IPC
+# error until postgres aborts with `PANIC: ERRORDATA_STACK_SIZE exceeded` and crashes the whole
+# server — after which immich can never reconnect. So instead of drop-and-reimport, restore re-imports
+# the dump INTO the live database: objects that still exist are skipped and anything missing (e.g. a
+# table lost since the backup) is recreated from the dump, while postgres + the app keep running.
+# The `search_path` rewrite is immich's documented restore step
+# (https://docs.immich.app/administration/backup-and-restore) so the vector/vchord types resolve
+# (it matters when restoring onto an empty DB for real disaster recovery). ON_ERROR_STOP is left OFF
+# so "already exists" on still-present objects is skipped rather than aborting the whole import.
