This test ensures that the server properly preserves and returns the same request ID in responses,
which is a fundamental part of the JSON-RPC protocol. The test initializes the server, sends
requests with custom IDs, and verifies that these IDs are correctly returned.

Adds comprehensive tests for lifespan functionality:
- Tests for both low-level Server and FastMCP classes
- Coverage for startup, shutdown, and context access
- Verifies context passing to request handlers
Introduce ReadResourceContents type to properly handle MIME types in resource responses. Breaking change in FastMCP read_resource() return type.
Github-Issue:#152
The server was ignoring mime types set on resources, defaulting to text/plain
for strings and application/octet-stream for bytes. Now properly preserves
the specified mime type in both FastMCP and low-level server implementations.
Note that this is breaks backwards compatibility as it changes the return
values of read_resource() on FastMCP. It is BC compatible on lowlevel since
it only extends the callback.
