List Interpreter Calls

Interpreted calls for this workspace, live ones first.

Serves the panel's monitoring list: who was rung, who was dialled, whether the two legs actually connected, and for how long. Interpreter rooms are identified by call_type = 'interpreter' (set at insert time in start_interpreted_call), so this never mixes in ordinary agent calls.

interpreter_id narrows the list to one interpreter's own calls (the per-interpreter detail page); it reads metadata->>'interpreter_id', which only rows written since that field was added carry.

offset + the returned total drive the panel's pagination. total is counted under the same filters as the page itself, so the control never offers a page that would come back empty.
