fix: kanban button

[austinpickett]

What does this PR do?

Kanban dashboard plugin buttons stop using ad hoc Tailwind className overrides (fixed heights such as h-8, borders, hover utilities). Each design-system Button uses size="sm" only so label alignment matches @nous-research/ui and avoids the leading-0 + grid items-center issue when an explicit height was applied.

Bulk actions used the hermes-kanban-bulk-btn class; that hook is removed from JSX. plugins/kanban/dashboard/dist/style.css instead targets .hermes-kanban-bulk > button and .hermes-kanban-bulk-reassign > button so compact height, padding, and hover stay the same. Inline Create still flexes via .hermes-kanban-inline-create > .flex.gap-2:last-child > button:first-of-type { flex: 1 }.

disabled is unchanged on Apply, dependency + parent / + child, and status actions; only extra opacity-40 / cursor-not-allowed utility classes were removed in favor of the Button component’s built-in disabled styles.

Changes Made

• plugins/kanban/dashboard/dist/index.js — all Buttons: size: "sm", drop className / cn(...) (filters, bulk bar, inline create, drawer, meta editors, description editor, dependency editor, status actions, error boundary).
• plugins/kanban/dashboard/dist/style.css — replace .hermes-kanban-bulk-btn with .hermes-kanban-bulk > button and .hermes-kanban-bulk-reassign > button; add inline-create first-button flex: 1 next to .hermes-kanban-inline-create.

How to Test

1. Run the Hermes web dashboard and open the Kanban plugin tab.
2. Filter row: Nudge dispatcher and Refresh — labels centered, hover OK.
3. Select card(s): bulk → ready / Complete / Archive / Apply / Clear — compact layout; Apply disabled until assignee (or path) allows action.
4. Task drawer: Comment, meta Save / Cancel, description Save / Cancel, + parent / + child, status buttons — correct enabled/disabled and layout.
5. Column inline create: Create still grows in the row; Cancel works.
