ci: bootstrap FR-flow callers on main

[LukasWodka]

Bootstrap commit: copies the FR-flow callers onto the protected branch so the FR gate activates on PRs targeting it.

After this lands, opening any PR to this branch will trigger fr-gate-caller.yml, which checks that contained items are in Ready for prod (or Ready for staging for staging-target PRs).
