Renames the new per-guardrail opt-out field from `disabled_global_guardrails`
to `opted_out_global_guardrails` to eliminate the one-character collision with
the legacy `disable_global_guardrails` boolean kill switch. Adds a type guard
on the new gate so a misnamed bool can't crash the guardrail check. Filters
duplicates out of the team-edit guardrail display for legacy teams that have a
global name persisted in `metadata.guardrails` from before this PR. Drops the
unused `isGuardrailsLoading` and `guardrailsError` destructures left in
AddModelForm after the hook refactor.
Adds Python tests for the new gate behavior (root, litellm_metadata, metadata,
non-matching name, empty list, malformed bool value, opt-in coexistence) and
extends useGuardrails.test.ts to exercise the global / optional partition
logic that the rebuilt hook performs in its `select` transform.
Wires the legacy kill switch and the new opt-out list together in the team
edit form so they can never fall out of sync:
- Toggling the kill switch reactively updates the Guardrails Select via
`onValuesChange` — switch on strips all globals from the selection, switch
off re-adds them. Existing opt-in extras are preserved either way.
- When the switch is on, global options in the Select are individually
disabled (greyed out) so the user can still manage opt-in guardrails but
cannot accidentally re-enable a global the kill switch is bypassing.
- The save handler writes both fields together: `disable_global_guardrails`
reflects the switch, and `opted_out_global_guardrails` is set to either
every global (when the switch is on) or the user's explicit opt-outs.
- `effectiveGuardrails` for the form's initialValues honors the kill switch
on legacy teams so the form opens in a state that matches what the runtime
gate is actually doing — fixes the visual lie where chips appeared active
while the switch was bypassing them.
The backend gate already reads the list as the primary path with the bool
as a fallback, so untouched legacy teams keep working until they get edited,
at which point they migrate naturally.
