Migrate search tool and get_board_items_page to use search_v2 endpoint

[damian-rakus]

Summary

Migrates the search tool and get_board_items_page tool from the deprecated search and search_items dev endpoints to the new search_v2 endpoint, which provides a unified search API with structured entity filters.

Changes

• search-tool.graphql.dev.ts — Replaced search query with search_v2. Uses SearchFiltersInput with entity-specific filters (boards/docs) instead of entity_types and top-level workspace_ids.
• get-board-items-page-tool.graphql.dev.ts — Replaced search_items query with search_v2. Uses SearchFiltersInput with items: { board_ids } filter.
• search-tool.ts — Updated searchWithDevEndpointAsync to build SearchFiltersInput per search type, using new query variables (limit instead of size). Response parsing updated from response.search to response.search_v2 with new typename constants (BoardSearchResult/DocSearchResult).
• get-board-items-page-tool.ts — Updated getItemIdsFromSmartSearchAsync to use search_v2 with structured filters. Results parsed by filtering for ItemSearchResult typename.
• search-tool.types.ts — Updated imports and typename constants from CrossEntityBoardResult/CrossEntityDocResult to BoardSearchResult/DocSearchResult.
• Generated types — Regenerated via yarn codegen to reflect new query shapes.
• Tests — Updated all mock responses, query string assertions, and variable expectations for both tools.
