chore: remove POWER_STEERING experiment remnants

Remove leftover powerSteering references that were missed during
the original POWER_STEERING feature removal in PR #10926.

- Remove from packages/types/src/experiment.ts (experimentIds, experimentsSchema)
- Remove from src/shared/experiments.ts (EXPERIMENT_IDS, experimentConfigsMap)
- Update tests to use PREVENT_FOCUS_DISRUPTION instead
- Clean up stale experiment IDs from test mocks
