fix: Show proper empty message instead of 'Loading' for empty DataTables

When a DataTable has 0 entries (e.g. empty queue, build with no resources),
the data-tables-api plugin's default emptyTable language string shows
'Loading - please wait ...' indefinitely. Override it with a proper message
for the queue table and the build action table.

Fixes #706
