🎨 style(channels-table): standardize operation component size to small

All operation-related UI controls in `ChannelsTable` (buttons, dropdowns,
switches, inputs, tags, etc.) now explicitly use `size="small"`.

Reasons & benefits:
- Creates a more compact and consistent look across the table and modals.
- Improves visual coherence between desktop and mobile views.
- Purely presentational; no functional logic is affected.

No database changes or API interactions are involved.
