Add select-all checkbox for tool category groups in MCP key form

[ruibaby]

What this PR does?

Adds a checkbox to each tool category header in the MCP access key form, allowing users to select or deselect all tools within a category at once. The checkbox shows an indeterminate state when only part of the category is selected.

The change applies to both the creation and editing modals, as they share the same AccessKeyForm component.

Why we need it?

Categories like post management contain many tools. Previously users had to toggle each tool individually; now a whole category can be granted or revoked with one click.

How to test it?

1. Open the "Create MCP key" modal in Console.
2. Click a category checkbox (e.g. 文章管理) and verify all tools in that category are selected, and the count updates accordingly.
3. Deselect one tool in the category and verify the category checkbox shows the indeterminate state.
4. Submit the form and verify the saved key's allowedTools matches the selection.
5. Repeat in the edit modal for an existing key.

pnpm check (Prettier, Oxlint/ESLint, vue-tsc, Vitest) passes locally.
