fix(checks list): scope summary bar counts to filtered checks

[checkly-rca-bot-angie]

Summary

When running checkly checks list --status failing (or any filter), the summary bar showed counts from all checks in the account while the total came from the filtered API response — producing a confusing mismatch:

✓ 6 passing    ✗ 1 failing    (1 total checks)

Root Cause

api.checkStatuses.fetchAll() has no filter — it always returns every check status. The activeCheckIds optional parameter on formatSummaryBar already existed for exactly this purpose but was never wired up from the list command.

Fix

Two small changes:

commands/checks/list.ts — pass current page check IDs as activeCheckIds when any filter is active, so counts reflect only visible checks.

formatters/checks.ts — always use totalChecks (server-reported) for the (N total checks) display, not activeCheckIds.size (page count).

Result:

# Before (--status failing, 1 of 7 failing):
✓ 6 passing    ✗ 1 failing    (1 total checks)   ← confusing

# After:
✗ 1 failing    (1 total checks)                   ← consistent

A regression test is included in checks.spec.ts.

Context

Reported in #cli — screenshot showing broken summary bar with checkly checks list --status failing.
