🐛 fix: preserve group filter when switching channel type/status

Ensure that the selected "group" filter (and other form search values) persist across
type tab changes, status filter updates, pagination, and page-size changes.

Changes include:
• loadChannels: added `searchParams` argument and now appends keyword, group and model
  query strings to API calls.
• refresh / page handlers / type tabs / status Select: now pass current form values
  to loadChannels, keeping filters intact.
• searchChannels: maintains active type and status filters when issuing search requests.
• Form.Select (searchGroup): triggers loadChannels when only group filter is active,
  preventing parameter loss.
• Minor cleanup and comment adjustments.
