Fork intervals-mcp-server: native OAuth + streamable-HTTP, no monkeypatch

- Bump mcp[cli] 1.22 -> 1.28.1 (negotiates MCP protocol 2025-11-25, matching
  current Claude clients; the old 2025-06-18 server never got a tools/list on
  the connector surface).
- Bake transport config into code: stateless_http + json_response for HTTP
  (single JSON body instead of a 34KB SSE stream, which the connector pipeline
  handles far more reliably).
- Bake Authentik OAuth (AuthSettings + JWT TokenVerifier) into intervals_mcp_server.auth,
  configured from MCP_ISSUER/MCP_RESOURCE/MCP_JWKS_URI/MCP_CLIENT_ID — removes the
  runtime FastMCP.__init__ monkeypatch from the k8s deployment command.
- Accept token audience with/without trailing slash (RFC 8707 clients use the
  slash-normalised resource metadata value).
- Dockerfile CMD runs the module (transport via MCP_TRANSPORT); add .gitea CI to
  build+push the image to git.farh.net/farhoodlabs/intervalsicu-mcp.

+Intervals.icu MCP Server
+
+This module implements a Model Context Protocol (MCP) server for connecting
+Claude with the Intervals.icu API. It provides tools for retrieving and managing
+athlete data, including activities, events, workouts, and wellness metrics.
+
+Main Features:
+    - Activity retrieval and detailed analysis
+    - Event management (races, workouts, calendar items)
+    - Wellness data tracking and visualization
+    - Error handling with user-friendly messages
+    - Configurable parameters with environment variable support
+
+Usage:
+    This server is designed to be run as a standalone script and exposes several MCP tools
+    for use with Claude Desktop or other MCP-compatible clients. The server loads configuration
+    from environment variables (optionally via a .env file) and communicates with the Intervals.icu API.
+
+    To run the server:
+        $ python src/intervals_mcp_server/server.py
+
+    MCP tools provided:
+        - get_activities
+        - get_activity_details
+        - get_activity_intervals
+        - get_activity_streams
+        - get_activity_messages
+        - add_activity_message
+        - get_events
+        - get_event_by_id
+        - add_or_update_event
+        - delete_event
+        - delete_events_by_date_range
+        - get_wellness_data
+        - get_athlete_power_curves
+        - get_custom_items
+        - get_custom_item_by_id
+        - create_custom_item
+        - update_custom_item
+        - delete_custom_item
+
+    See the README for more details on configuration and usage.
