fix: correct MCP SSE launch, shebang ordering, and E2E helper scripts

- execution_mixin: replace non-existent FastMCP.create_app() with the
  repo's working low-level SSE transport pattern (connect_sse +
  handle_post_message), matching mcp/mcp_server.py; normalize base_path
  leading slash. Fixes AttributeError at MCP server startup.
- examples (36 files): move '# praisonai: skip=true' below the shebang so
  direct execution still works; directive stays within the runner's
  first-30-lines scan.
- failover_example: display real 'last_error' instead of unmodeled
  'failure_count' (which always printed 0).
- scripts/apply_e2e_batch3_*.py: make skip insertion shebang-aware, wire
  the previously-uncalled fix_mcp_env_examples(), and make the E2E report
  path a CLI argument (defaulting to the audit path).

-"""Regression tests for Telegram callback-payload store wiring (issue #3312).

-The core SDK can encode an overflowing ``reply``/``select`` value under a short
-``@<ref>`` and resolve it back — but only when the *same* store is shared by the
-render side and the inbound registry. These tests assert the production Telegram
-renderer + registry actually share one store, so long option values (URLs, file
-paths, IDs) round-trip losslessly past Telegram's 64-byte inline-callback cap
-instead of being replaced by an unrecoverable hash.
