Remove redundant search bar from Home, rename page filters

- Remove SearchInput from Home page (use GlobalSearch in header instead)
- Rename "Search packages..." to "Filter packages..." on ProjectPage
- Rename "Search tags..." to "Filter tags..." on PackagePage
- Update FilterChip labels from "Search" to "Filter"

This differentiates the global search (header) from page-level filtering.
