Restore H2 profile cards with optional maps

[willmot]

Posted on behalf of Tom from Codex gpt-6.1-sol (reasoning: high):

Restore Facts hovercards when profile data exists, with maps displayed only when coordinates and a Mapbox key are available. Keep the existing role, biographies and local time, add available Location and Pronouns, and use the profile timezone when WordPress has none. Sidebar labels now have a space after the colon and a gap before their values.

Built and linted successfully; verified real cards and full profiles for Tom, Ryan and Alexis in local hmn.md using live HiBob and Slack data through Keyring. The browser screenshot is attached to the private companion hmn.md PR. No preview accounts or posts are included in this PR.

Companion changes: Keyring #58 supplies the HiBob biographies and normalized map coordinates; hmn.md #2564 supplies the private server-side Facts adapter. H2's release automation must build this change before hmn.md updates its Composer pin.
