fix: litestream single replica + disable healthcheck gate

v0.5.8 dropped multi-replica support — remove the local path replica,
keeping only R2. Also disable litestream's healthcheck so deploy's
`up --wait` isn't gated on the backup service.

 - Legal pages: replaced home address with virtual office address (c/o COCENTER, Koppoldstr. 1, 86551 Aichach) in all four legal templates (`imprint_de`, `imprint_en`, `privacy_de`, `privacy_en`, `terms_de`)
 
 ### Fixed
+- Litestream: remove local-path replica — v0.5.8 dropped multi-replica support (`"multiple replicas on a single database are no longer supported"`), keeping only the R2 replica
+- Deploy: disable litestream health check so it no longer blocks `up --wait`
 - Deploy: write nginx router config *before* starting containers so the router health check (`nginx -t`) passes on first deploy or after volume wipe
 - Deploy: pre-migration DB backup added to `deploy.sh`; on health-check failure the DB is restored to pre-migration state (prevents old slot from running against new schema)
 - Migrations: removed all `conn.commit()` and `executescript()` calls from `up()` functions in 0000, 0011, 0012, 0013, 0014, 0015 — restores batch-atomicity guarantee (`executescript` issued implicit COMMITs, breaking rollback on failure)
