Make profile state filters multi-value

Address PR review feedback on the profile-state split: SAML sign-in now
activates a pending profile, deactivation counts owners against the
profile's own organization to close a last-owner bypass, the migration
leaves historical activated_at/deactivated_at NULL rather than
fabricating timestamps, and pending members are no longer rendered with
the deactivated (faded) styling.

Drop the single-value state filter in favor of the multi-value states
across the profile and signatory surfaces. Remove ProfileFilter.state
(only states[] remains) and convert the signatures profileState filter
to profileStates. Turn the console people filter, the CLI
"user list --state" flag, and the n8n listUsers and getAllSignatures
state inputs into multi-select controls, where an empty selection means
all states.
