Pause-time token emission now draws only from the recipient set each API
surface is allowed to act on (emit ⊆ validate), so the CLI/OpenAPI caller is
never handed a token the resume endpoint would reject as 404 (WTA-867).
A form's recipients are partitioned once, per surface, into a single
FormDisposition: the surface-actionable recipient yields `form_token`, while
the rest are reported as `approval_channels` (e.g. ["email", "console"]) so the
caller is told where approval actually happens. Token and channels are two
projections of one decision (disposition_for_surface) loaded by one recipient
query (load_form_dispositions_by_form_id); the live pause path and the
reconnect snapshot path consume the same FormDisposition so they cannot drift.
RecipientType carries its user-facing approval-channel label as an enum tuple
value, set in __new__, so a new recipient type cannot be declared without one.
Tests: consolidate recipient/disposition/enrich tests into parametrized
matrices, add CONSOLE-surface and empty-token coverage, extract a shared fake
session for the pause-event tests.
