Tests for intervals_mcp_server.tools.athlete.

Covers the athlete-context read tools (get_athlete_profile, get_sport_settings,
get_athlete_summary): request shape, sport filtering, formatting of realistic
fixtures, and the empty / error / credential branches. Default caller credentials
come from the autouse fixture in conftest (athlete ``i1``).
