feat: add Slack ops data checks

[akshaymagapu]

Summary

Adds Slack ops commands for checking and backfilling the LLMO agentic traffic data path.

Commands available in this PR

Check CDN aggregate inputs for a traffic date:

@spacecat-dev check cdn logs status [YYYY-MM-DD] [siteId=<siteId>|baseUrl=<url>]

Backfill daily DB import for one site:

@spacecat-dev backfill-llmo baseurl=<url> audit=cdn-logs-report mode=db date=YYYY-MM-DD

Backfill daily DB import for all enabled sites:

@spacecat-dev backfill-llmo baseurl=all audit=cdn-logs-report mode=db date=YYYY-MM-DD

Check agentic traffic DB readiness directly from DB tables:

@spacecat-dev check agentic traffic db status [YYYY-MM-DD] [siteId=<siteId>|baseUrl=<url>]

Omit siteId/baseUrl to check all enabled sites.

What the checks verify

• check cdn logs status: S3 aggregate CDN log inputs are present for the date.
• check agentic traffic db status: row and hit totals exist in agentic_traffic, agentic_traffic_daily, and the matching agentic_traffic_weekly week.
