fix(databases): use name not description for API alignment

The Hotdata API renamed the database identifier field from `description`
to `name`. This updates:

- `try_resolve_database`: filter by `d.name` instead of `d.description`
  so that `hotdata databases get <name>` works against the new API
- `databases set`: accept the database id directly rather than resolving
  by name/description — the id is unambiguous and always available
- Error messages and help text: "id or description" → "id or name"
- Tests: update mock payloads to return `name` (not `description`)
