fix(rmcp-macros): replace deprecated *Param type aliases with *Params (#727)

The `#[task_handler]` macro generates code using deprecated type aliases
(`PaginatedRequestParam`, `CallToolRequestParam`, `GetTaskInfoParam`,
`GetTaskResultParam`, `CancelTaskParam`) that were renamed to `*Params`
in rmcp 0.13.0. This causes 5 deprecation warnings for every crate
using the macro.

Update all references to use the canonical `*Params` names:
- `PaginatedRequestParam` → `PaginatedRequestParams`
- `CallToolRequestParam` → `CallToolRequestParams`
- `GetTaskInfoParam` → `GetTaskInfoParams`
- `GetTaskResultParam` → `GetTaskResultParams`
- `CancelTaskParam` → `CancelTaskParams`

Also fix the corresponding doc examples in `lib.rs`.
