feat(blocks): add external-service url to block metadata (#5032)

* feat(blocks): add external-service url to block metadata

- Add optional `url` field to BlockMeta for the integration's own homepage (e.g. exa.ai, salesforce.com), distinct from docsLink which points at Sim's docs
- Populate `url` on all 209 integration blocks with verified homepages (protocol/internal blocks without a single vendor site are left without one)
- Document the field in the add-block skill and command, with rule + checklist entries
- Backfill missing docsLink on dspy and add a few accurate tag entries

* fix(blocks): drop tag backfills to avoid catalog drift

Revert the agiloft/exa/tailscale tag additions; integrations.json (used by landing/SEO) is not regenerated here, so the expanded tags would diverge from getAllBlockMeta(). Keep the url additions, which are not projected into integrations.json.

* fix(blocks): correct inaccurate tool URLs flagged in review

- spotify: open.spotify.com (web player) -> www.spotify.com brand homepage
- sts: point to the STS API reference (aws.amazon.com/sts 404s; STS has no standalone product page) instead of the shared IAM page
- microsoft: drop locale-specific /en-us/ segments across Excel, Teams, OneDrive, SharePoint, Outlook, Dataverse, Planner, Entra ID, and shorten OneDrive/Outlook to stable product roots
