mctp/server: add mock-transport test suite

Add a comprehensive set of integration and unit tests for the MCTP server
that run without the I2C transport layer. A BufferSender mock replaces
the real I2C sender; no transport hardware or system linker is required.

New files:
- tests/common/mod.rs     -- shared fixtures: BufferSender, DroppingBufferSender,
                             DirectClient, DirectListener, DirectRespChannel,
                             DirectReqChannel, transfer()
- tests/server_unit.rs    -- unit tests for Server methods: EID management,
                             handle alloc/free, try_recv, inbound routing,
                             oversized payload, register_recv + timeout
- tests/integration.rs    -- multi-fragment reassembly, concurrent listeners,
                             echo via MctpListener+MctpRespChannel traits,
                             MctpReqChannel, drop_handle mid-flight,
                             response EID/tag threading

Updated files:
- tests/echo.rs           -- refactored to use common/ (no duplicated fixtures)
- tests/dispatch.rs       -- refactored to use common/; added edge-case tests:
                             malformed request, unknown opcode, Recv with no
                             message, Unbind
- BUILD.bazel             -- four new rust_test targets, one per test file
- README.md               -- document new test layout and Bazel invocations

All four Bazel test targets pass:
  bazel test //services/mctp/server:mctp_server_{echo,dispatch,unit,integration}_test
