Mick 999c0f7b83 Add Parser Quality page: Live Event Sampler, Field Population Rate, Parser Test Runner
- New /api/quality router with three endpoints:
  sample-events: pull raw events from a source via PowerQuery
  field-population: measure % of events with each SDL field populated;
    surfaces dataSource.name correctly (100% when filtered by it) and
    returns fields_seen_in_sample so you can see what IS being extracted
  test-parser: converts SDL \$field=pattern\$ format strings to Python
    named-group regex and tests against a pasted raw log line
- New "Parser Quality" nav item and page with all three tools
- Home page card added for Parser Quality
- Field population UI shows per-field colour-coded progress bars plus
  a chip list of fields actually present in the sample
