hermes 2d57173e31 fix: CodeGit looked like an empty black box - hardcoded panel height + cache
Reported as "why can't i see anything from codegit its just a black box".

NOT a codegit bug. Verified first, exhaustively, through the authenticated API:
  overview  200    940 bytes
  log       200  79596 bytes   (full commit history)
  transfer  200   1460 bytes
  config    200   1174 bytes
no JS errors in the console; every DOM helper codegit calls exists.

ROOT CAUSE 1 - a generic CSS rule hardcodes a height
  theme/modules/common/_panel.scss -> theme/main.min.css:
    panel { ... height: 500px; ... }
  That forces EVERY modal panel to a fixed 500px box. Measured live:
    #dialog            404px  (clamped by max-height:70vh + overflow-y:auto)
    #codegit panel     500px, while its content is only 119px
    toolbar ("Branch") top 620 vs dialog bottom 490 -> OUTSIDE the modal
  So ~380px of the dialog was empty dead space and the Branch line rendered below the
  modal, invisible. Fixed to height:auto with max-height:58vh (long content still scrolls):
    before: panel 500 -> toolbar top 620, dialog bottom 490 (outside)
    after:  panel 136 -> toolbar top 256, dialog bottom 279 (inside)
  _panel.scss updated too so the source does not contradict the shipped CSS.

ROOT CAUSE 2 - the fix was invisible because of the browser cache
  Atheos serves theme/main.min.css and the generated bundles from stable URLs with no cache
  headers, so browsers legitimately reuse their cached copy - which is why the first attempt
  appeared to do nothing. nginx now sends Cache-Control: no-cache, must-revalidate for
  *.css/*.js: caching still works (cheap 304s) but changes are always picked up.

Adds
  scripts/fix-panel-layout.sh   idempotent re-apply for both fixes (lost on update-atheos)
  docs/known-issues.md §4, §5   both findings, with the measurements

Tests (44 passed, 1 failed - the failure is branch protection, a genuine open item)
  + panel must not be fixed at 500px
  + theme CSS must send Cache-Control: no-cache
