feat(open-swe): re-add Fable 5 behind an admin toggle (Bedrock) (#172)
* feat(models): re-add Fable 5 with admin disable toggle (port of upstream #1677)

* refactor(models): convert re-added Fable 5 to Bedrock model IDs

* fix(open-swe): correct Fable copy to describe provider data sharing, not ZDR

The ported admin toggle description and code comments described Fable 5 as
incompatible with Zero Data Retention. That is backwards: Fable 5 requires
the account to opt into Bedrock provider_data_share — prompts/completions are
retained and shared with Anthropic (up to 30 days, incl. human review). The
old UI copy would lead an admin to believe the opposite of what enabling the
toggle does. Reword the toggle description and the gate_fable_model /
team_settings comments accordingly. Still off by default. Refs #171.
