Changelog

This reverts commit 1fd77727299d661a526e37e61f0b5634561c56bc.

The detail dialog was shown via ShowDialog(this) where 'this' was the

ApiDocsWindow. On macOS, child dialogs are constrained to the parent

window's bounds, causing long response content to get clipped. Fixed by

parenting the detail dialog to the main window (Owner) instead.

Also added bottom padding to the detail window's outer ScrollViewer.

New OpenApiSpecGenerator service builds a full OpenAPI 3.1.0 spec from all

registered IApiProvider routes (plugin + shell). Exports as JSON (pretty-printed

via System.Text.Json) or YAML (simple recursive JsonNode walker — no external

dependency). Includes paths, parameters, request/response examples, apiKey

security scheme, tags per plugin, and shell routes (status, routes).

Two new link-buttons "(JSON) | (YAML)" appear below "View Documentation" in

Developer Settings. Each opens a SaveFileDialog and writes the spec to the

chosen path.

Prevents horizontal overflow when the subtitle and link button

compete for space in a narrow settings panel.

Both ApiDocsWindow and ApiRouteDetailWindow ScrollViewers lacked

HorizontalScrollBarVisibility="Disabled", allowing monospace code blocks

and inline runs to overflow the window width. Content now constrains to

the window width with text wrapping.
