agent: cap icon at 5em, fix overflow menu hidden-state (#411)

Browse source 
Two regressions from #394 that landed once mara deployed:

1. **Icon way too big** — `.agent-icon { height: 100%; aspect-ratio: 1 }`
   sized off the parent's height. With `align-items: stretch` on the
   header and `min-height: 6em`, the `<img>`'s intrinsic dimensions
   fed back into the flex container's height calculation and pushed
   the header (and the icon stretched to fill it) far past 6em — the
   icon ended up dominating the page.

   Switch to explicit `width: 5em; height: 5em` (header content area
   = 6em min-h - 2 × 0.5em padding). `align-self: flex-start` so a
   state-row wrap doesn't drag the icon down with it.

2. **Overflow menu always visible** — `.overflow-menu { display: flex }`
   in author CSS overrode the `[hidden]` UA rule (`[hidden]
   { display: none }` has the same specificity). With nothing hiding
   it, the menu rendered at viewport 0,0 by default (no top/left set
   on the popover until JS opens it), so the operator saw `↑ dashboard
   / ↻ rebuild container / ↻ new claude session` stacked at the
   top-left of every page load.

   Split the rule: `.overflow-menu` keeps the chrome (frosted bg,
   position fixed, z-index, border, padding); `.overflow-menu:not([hidden])`
   carries `display: flex`. Now `[hidden]` wins when set, no menu
   shown until the trigger opens it.

agent.css 22.4kb → 22.5kb.
