Replace ad hoc local types with SDK schema types across the Sampling
and Elicitation group components.
- SamplingRequestPanel: accept `request: CreateMessageRequestParams` +
`draftResult: CreateMessageResult` instead of 16 flat props; derive
messages, model preferences, and parameters from the request object;
drop `tools`/`toolChoice` (not in MCP 2025-11-25 CreateMessageRequest)
- InlineSamplingRequest: accept `request: CreateMessageRequestParams`;
derive messagePreview and modelHints from the request
- ElicitationFormPanel: accept `request: ElicitRequest['params']` +
`serverName`; pass requestedSchema directly to SchemaForm
- ElicitationUrlPanel: rename `elicitationId` to `requestId`
- InlineElicitationRequest: accept `request: ElicitRequest['params']`;
discriminate form vs URL mode on request shape instead of `mode` prop
- PendingClientRequests: unchanged (children-based wrapper)
- Delete local `SamplingTool` type
- Update all stories with real SDK type fixtures
