Handle mise monorepo_root rename for Immich

Updated both Immich setup scripts (`ct/immich.sh` and `install/immich-install.sh`) to patch `mise.toml` before running `mise //:plugins`. The change ensures `monorepo_root = true` is present while retaining `experimental_monorepo_root = true`, so plugin builds work across old and new mise versions after the v2026.7.0 key rename.
