fix(newos4): workspace re-opened the modules panel every tick; picker lost two cards; commander was blackHEADv4.6.156main

Three defects reported against v4.6.155, each reproduced before touching code:

1. 'the modules tab keeps opening' (workspace). api.capture() runs dispatchCommand() for real, and
   the Modules card called bare 'modules' — whose only effect is terminal.openModuleManager().
   Every 15 s refresh re-opened the panel (measured: #module-manager display:flex at t+9s and
   t+18s). The card now captures 'listmods' (same inventory as text), and api.capture() refuses
   UI-only commands outright so a future card cannot reintroduce it.

2. 'the picker got reduced to 4 items'. showPicker() used this.list() once four modes were
   registered — but modes are lazy, so that is 'modes you have already visited'. It now always
   renders the six in level order, taking registered specs for label/tagline.

3. 'commander is mostly black' on a phone. The base sheet's #ui-root rule used
   body[data-ui-mode]:not(...) #ui-root (1,2,1) and therefore beat every mode's own
   body[data-ui-mode='x'] #ui-root (1,1,1): commander/studio/cockpit asked for display:grid and got
   flex column. Commander collapsed to a 253 px centre column in an 844 px page with both rails
   hidden. Base specificity is now (1,0,0) with an explicit !important hide for classic/boot, and
   the commander phone query pins grid-template-rows: minmax(0,1fr) so the single row fills.

Measured after: picker 6 cards after visiting four modes; #module-manager stays display:none
across a refresh cycle; commander display:grid, phone centre 390x810 with a 673 px terminal,
desktop 232/788/260 columns. probe-ui-modes.py --cycle -> ALL PASS, 13 checks; shell test 25/25.
