Merge pull request 'pack: v0.39.1 — bnstoolkit 0.6.1 sub-panel sizing hotfix' (#79) from hotfix/sub-panel-sizing into main

Hub screen showed blank content area: title bar + 3 buttons rendered,
but the status panel in between was empty. Same latent bug affected
every screen with a sub-panel (Tier, Counting House, Bounty, Plot,
Quest Log).

Root cause: FTB Library's Panel.refreshWidgets order is
addWidgets → recurse-into-child-panels.refreshWidgets → alignWidgets.
So when the parent's alignWidgets sets a sub-panel's size, the
sub-panel's children have already aligned themselves using the
sub-panel's pre-size dimensions (0x0). Every Row got setSize(0, 12)
→ invisible.

Fix: size sub-panels BEFORE add() in the parent's addWidgets so the
recursive refreshWidgets sees correct dimensions. Parent's
alignWidgets now only positions the top-level action buttons.
