fix: accept sites fmt|cbs|pdx|roam (tenancy 0.7.x) and keep the identity read grant alive across tunneller rewrites — 0.1.10

deployd#3 (DD-0620): every kit for a backend registered since 2026-09-08 died at `--site`.
env-dev-08 (2026-09-11..13): two days of "identity is not readable" ticks — ziti-edge-tunnel
re-creates the file with mode 0600, the ACL mask goes to ---, group membership stops helping.
identity-acl.sh + monky-deployd-identity-acl.path re-apply the grant on every directory change.

Doc-Drift: DD-0620 fixed
Closes #3
