* fix(ssh): allow a host's orca CLI to control Orca by default, and stop resetting saved choices
An absent allowRemoteCliControl now means on; only an explicit false turns the
desktop browser bridge and relay-era orchestration commands off. Removes the
one-time reset of saved true values, the consent stamp writes and the reset
notice, which would have silently turned off hosts upgraded from stable.
* fix(ssh): keep the CLI control choice when adding a host from the sidebar
* fix(ssh): read an older client's omitted CLI control switch as off over RPC
* fix(ssh): check the managed fence before routing settings in browser bridge candidates
