[Improve] One tool row for every integration tool dialog

[daniel-lxs]

Summary

The two integration tool dialogs drew the same list differently. Built-in integrations used a switch, a readable tool name, and no description; custom MCP servers used a checkbox, the raw tool name in mono, and a description. They were built at different times and nothing tied them together.

Both now render one row from the shared tool list:

• Checkbox for enable/disable. The change is staged until the dialog's Save, which a switch misrepresents, and it now reads differently from the approval controls beside it, which do save immediately.
• Readable tool names everywhere ("Resolve Library Id"), with the integration's own name dropped when the tool name repeats it. The raw name stays available as the label's tooltip.
• Descriptions in both dialogs, clamped to two lines behind Show more.

The row, the name formatting, and the description toggle moved into the shared list, so each dialog passes only its enabled state and toggle handler.

Testing

• The dialog's own suite now covers the unified row against the real component (checkbox, readable name with the raw name as its title, description shown, no switch). Tests that pinned the old switch labels and raw names were updated. The settings suites pass.
• Checked live on a local stack.
