fix(s8): add scheduler runtime schema foundation

Add columns + index foundation for S8 watch scheduler runtime, plus
detection state table for pre-creation hit/miss debouncing. No service
or job logic wired up in this commit; only schema + entity registration.

ado_s8_watch_rule: 15 runtime columns (next_run_at / last_run_at /
last_status / last_error / last_duration_ms / last_run_id / lock_token
/ locked_by / lock_until / running_started_at / consecutive_failure_count
/ paused_until / pause_reason / trigger_count_required default 1 /
recover_count_required default 1) + 3 indexes (dispatch / lock_until /
rule_code; uses 'enabled' not 'is_enabled').

ado_s8_exception: 2 runtime columns (consecutive_hit_count default 1 /
consecutive_miss_count default 0) for post-creation debouncing.

new table ado_s8_rule_detection_state: pre-creation debouncing state
keyed by (tenant, factory, rule_code, dedup_key); UNIQUE
uk_s8_rule_detection_state_dedup; no soft-delete.

dev/test (aidopdev) initialization: stagger next_run_at, normalize
trigger/recover_count_required to 1.

Verified: dotnet build 0 error; CodeFirst auto-applied DDL on backend
restart; SchedulerJob first tick after migration succeeded
(hits=5 created=0 skipped=5 failed=0); demo rules id=10/11/12 still
enabled; exception_type baseline (tenant=0 factory=0 enabled=1) = 3
unchanged before/after migration.
