Replace mock pass data with paginated, filterable data fetching on /passes

[Lakes41]

Difficulty: Intermediate
Type: feature

Background
The /passes route currently reads directly from apps/dashboard/lib/mock-data.ts with no pagination or filtering, which won't scale once real data sources are wired in.

Problem
All passes are loaded and rendered client-side in a single pass, with no way to filter by pass type, status (active/expired/revoked), or guild, and no pagination controls.

Expected outcome
The passes table supports server-side-style pagination (even against mock data, structured to be backend-ready), plus filter controls for status and guild, and a search box for pass name/ID.

Suggested implementation

• Add a getPasses({ page, pageSize, status, guildId, query }) function in apps/dashboard/lib/mock-data.ts that filters/paginates the mock array.
• Add pagination UI (prev/next + page size selector) to the passes table component.
• Add filter dropdowns and a debounced search input above the table.
• Keep filter state in the URL query string so filtered views are shareable.

Acceptance criteria

• Passes list paginates in fixed-size pages
• Filtering by status and guild works and updates the URL
• Search filters by pass name/ID
• No regression in existing passes page tests/build

Likely affected files/directories

• apps/dashboard/lib/mock-data.ts
• apps/dashboard/app/passes/ (or equivalent passes route/components)
• packages/integration-client (if pass types need extending)
