fix(mcp): upgrade to MCP SDK 2.3.0 and raise the per-event SSE size cap (#47034)
* fix(mcp): upgrade to MCP SDK 2.3.0 and raise the per-event SSE size cap

MCP SDK 2.x reads Streamable HTTP responses through httpx2's SSE parser,
which rejects any single event over 1 MiB, so a large tools/call result
failed with 'SSE stream ended without a response'. mcp 2.3.0 exposes
max_sse_event_size, and MCPClient now passes a 64 MiB default,
configurable with LITELLM_MCP_MAX_SSE_EVENT_SIZE_BYTES

* fix(mcp): fall back for invalid SSE event limits

* test(mcp): verify configured SSE limits and recovery

* chore(mcp): remove redundant dependency comment
