fix(modal): keep body-portaled dropdowns above their tool modal at any stack depth (#4720) (#4724)

* fix(memory): keep the Brain memory item menu above the modal at any stack depth

The memory item "⋮" dropdown is portaled to <body> with a hardcoded
z-index of 10001. Tool modals, however, get a monotonically increasing
z-index from modalManager's bring-to-front counter (_modalTopZ), which
climbs unbounded as modals are opened/restored over a session. Once that
counter passes 10001, the Brain modal stacks above the body-portaled
dropdown, so the menu renders behind the panel — visible only where it
spills past the modal's edge (#4720).

Derive the dropdown's z-index from the owning modal's current z-index
(+1), keeping 10001 as a floor for the common low-counter case, so the
menu always sits just above its modal however high the counter has climbed.

Verified with document.elementFromPoint at the dropdown's location: with a
high modal z-index the old build returns the modal at every sampled point
(menu behind); the fixed build returns the dropdown (menu on top). The
default low-counter case is unchanged (z stays 10001).

* refactor(modal): route body-portaled dropdowns through a shared topPortalZ() helper

The hardcoded z-index:10001 the Brain memory menu used (#4720) is the same
literal shared by ~16 body-portaled dropdowns across calendar, cookbook,
cookbookServe, documentLibrary, emailLibrary, gallery, notes, emojiPicker and
memory — each renders behind its owning tool modal once modalManager's
bring-to-front counter climbs past the literal over a long session.

Promote the per-dropdown fix into a single topPortalZ() helper in
toolWindowZOrder.js — the existing source of truth for tool-window z, already
imported by modalManager's _bringToFront and notes.js — returning
max(topToolWindowZ(), dock-chip floor) + 1, so a portaled dropdown always sits
just above the live tool-window stack however high the counter has climbed.
Route all 16 sites through it. The slashCommands tour tooltips and the
cookbookServe VRAM dialog are intentionally left out (neither is a modal-owned
portaled dropdown).

Add tests/test_portal_dropdown_z_js.py covering the helper, including the #4720
scenario (modal counter at 99999 -> dropdown at 100000). Existing
test_notes_z_order_js.py stays green.
