ui: focus scan name input and start scanning on Enter

'Profile from card' and 'New snapshot' now focus the name field when the
dialog opens, and Enter in that field starts the scan
(profilerScanNameKeydown, ignored while the Scan button is disabled).
Tests for the key handler and the input wiring; SW cache v98 -> v99.
