1. Backend
• `controller/channel.go`
– Added pagination (`p`, `page_size`) support to `SearchChannels`.
– Added independent `type` filter (keeps `type_counts` unaffected).
– Returned `total`, `type_counts` to match `/api/channel/` response.
2. Frontend
• `ChannelsTable.js`
– `loadChannels` / `searchChannels` now pass `p`, `page_size`, `id_sort`, `type`, `status` correctly.
– Pagination, page-size selector and type tabs work for both normal list and search mode.
– Switch for “ID sort” calls proper API and keeps UI state in sync.
– Removed unnecessary `normalize` helper; `getFormValues` back to concise form.
Result
• Search mode and normal listing now share identical pagination and filtering behavior.
• Type tabs show correct counts even after searching.
• “ID Sort” toggle no longer inverses actual behaviour.
