fix(repositories): keep deep-linked ?page=N when search hasn't changed

[RenzoMXD]

Summary

The repositories leaderboard's pagination snaps back to page 1 after every click and on direct loads of /repositories?page=N. The table routes DebouncedSearchInput's onDebouncedChange through useDataTableParams.setFilter('search', ...), whose useCallback closes over react-router-dom's setSearchParams. That ref is recreated on every URL change, so every setPage(N) recreates the callback, which re-fires the wrapper's mount-anchored debounce effect. The fired commit deletes ?page via the filter's default resetPageOnChange, snapping the table back to page 1 right after the click.

Same root cause #1108 fixed for MinerPRsTable. This PR applies the same callsite gate: keep the latest committed searchQuery in a ref and skip setFilter('search', ...) when the wrapper hands back the value we already hold. Typing a new search still commits normally and resets ?page as intended; the mount fire and any re-render driven by an unrelated URL change no longer touches the page slot.

Closes #1247

Type of Change

• Bug fix
• New feature
• Refactor
• Documentation
• Other (describe below)

Testing

Verified locally against npm run dev:

• Direct load /repositories?page=1 retains ?page=1 and renders rows 13–15 of 15.
• "Go to next page" / "Go to last page" advance to ?page=1 and stay (no snap-back).
• Typing into the search input still commits the filter after the debounce and resets ?page so the result list starts at page 1.
• npm run build — clean
• npm run lint — --max-warnings 0 clean
• npx prettier --check — clean

Checklist

• New components are modularized/separated where sensible
• Uses predefined theme (e.g. no hardcoded colors)
• Responsive/mobile checked (behavior is URL/query only)
• Tested against the test API
• npm run format and npm run lint:fix have been run
• npm run build passes
• Screenshots included for any UI/visual changes
