web: render the per-port tables in physical port order

The firmware emits every per-port array in logical port order, which on a
board with a remapped port table (SWGT024: phys_to_log = {4,5,6,7,8,3,...})
is 6, 1, 2, 3, 4, 5. The old pages iterated over physical port numbers and
looked each entry up; the single-page app rendered the arrays as received,
so the ports, spanning tree, EEE and bandwidth tables and the dashboard
strip came out in logical order, and the strip put the SFP marker and the
detail view on the wrong port.

Sort every array by portNum on receipt so index i is port i+1 throughout.
