improvement(ui): consolidate the disclosure chevron and order resource menus like the sidebar - #6447

…e menus like the sidebar

#6400 aligned the workflow-tree folder chevron to the sidebar section header
(16px/100ms -> 14px/150ms) but left the literal hand-copied in three files, so the
next edit could drift them apart again. Extracts `disclosureChevronClass` into
chip-chrome as the single source and points the section header and both sidebar
trees at it. Adds `chipIconSlotClass` for the 16px slot that ChipChevronDown,
ChipSelect, ChipDropdown and ChipDatePicker each re-derived.

Both Back buttons rendered a ChevronDown rotated 90deg at 10px — wrong glyph, and
4px under every other chevron in the app; they are now ChevronLeft at 14px in that
shared slot. The sidebar file tree drew hand-inlined SVGs at strokeWidth 2 next to
the workflow tree's emcn icons at 1.55, so the two trees showed different folder
glyphs; both now use the emcn set. Its file rows also indented by the chevron's
width alone, landing their icon 4px left of a folder's and 2px smaller despite the
comment claiming they lined up — they now clear the chevron plus the row gap at
the same 16px size.

Separately, the chat `+`/`@` resource menus rendered every foldered family as a
submenu and only then the flat ones, which pinned Workflows to the top regardless
of any ordering. Adds `RESOURCE_MENU_ORDER` mirroring the sidebar top-down and
merges both kinds into one ordered pass, so the menus read Integrations, Chats,
Tables, Files, Knowledge Bases, Logs, Workflows, then Browser and Terminal on
desktop. Documents the general rule in .claude/rules/sim-list-ordering.md.

…reads them

An audit of every menu, tab strip, and context menu against the surface the user
already reads those items on turned up six more divergences.

The table row context menu put View execution before the Run/Re-run/Stop cluster
while the action bar puts it after, so the same four actions read in two orders;
the menu now follows the bar. The Files, Tables, and Knowledge empty-space create
menus were each the exact reverse of their own page header, and each named the
same action differently ("Create table" vs "New table", "Add knowledge base" vs
"New base") — reversed to match, labels unified.

Recently Deleted led with Workflows and buried Chats last, and put Knowledge Bases
ahead of Files; it now follows the sidebar after the default All tab. The command
palette hoisted Workflows from last to second for the same reason, and is now in
sidebar order too. Chats stays first in both, so the palette's Enter default is
unchanged.

Drops the unused RESOURCE_TYPES export: nothing consumed it, and its declaration
order was nearly the inverse of RESOURCE_MENU_ORDER, so the first consumer to map
it would have silently rendered a backwards menu.

Not included: buildUnifiedSettingsNavigation never applies its own unified.order
and returns registry declaration order instead. Nothing user-visible today (the
sidebar re-sorts before rendering) but navigation.test.ts pins the unsorted order
as canonical, so fixing it means changing that test — worth doing deliberately
rather than inside this PR.
