Fix pagination logic and extract PAGE_SIZE constant

[Copilot]

Addresses code review feedback on pagination implementation and naming conventions in the home search module.

Pagination Logic

• Track hasMoreUsers and hasMoreProjects states to prevent fetching when API returns fewer than PAGE_SIZE items
• Add loading checks to prevent duplicate concurrent requests
• Applied to 4 pagination locations: search projects/users, search sidebar users, home content projects

Before:

endReached={() => {
  const nextPage = Math.floor(projects.length / 10) + 1;
  fetchProjects(searchTerm, nextPage);
}}

After:

endReached={() => {
  if (!isLoadingProjects && hasMoreProjects) {
    const nextPage = Math.floor(projects.length / PAGE_SIZE) + 1;
    fetchProjects(searchTerm, nextPage);
  }
}}

Code Quality

• Extract PAGE_SIZE = 10 constant, use across 8 pagination locations
• Type activeModule as 'search' | 'home' instead of string
• Rename HOME_ROUTES → homeRoutes per camelCase convention
• Remove unnecessary setTrendingProjects from useCallback dependencies

State Management

• Reset users state when clearing search to prevent stale data
• Simplify handleSearchChange - navigation only on submit/clear, not every keystroke
