[OP-17736] route spec files via solution-style root config

[akabiru]

https://community.openproject.org/wp/OP-17736

Opening a *.spec.ts in an editor surfaces phantom Cannot find name 'describe' / 'it' / 'expect' errors. The TypeScript language server resolves a file against the nearest tsconfig.json, and the frontend root config declared no files or include, so it globbed spec files in without the vitest/globals types that tsconfig.spec.json provides.

This restores the Angular CLI default solution-style root config (files: [] plus references to the app and spec projects) so the language server routes each file to the project that owns it. The app project's include is broadened to the whole src tree (excluding specs and the Vitest entry files) so every non-spec file still belongs to a project — without this, ESLint's projectService can no longer resolve most of src/app.

Broadening the app include compiles the whole tree, which surfaces two dead, unreferenced components that no longer build (GlobalSearchTabsComponent, ViewSettingsModalComponent); both are removed. The unused tsconfig.compodoc.json (referenced nowhere) is dropped as well.

@myabc This mainly would affect nvim users as the rootdir changes in context of the buffer: i.e. when within the frontend/ dir- the first root is seen as that which messes up the TS language server to show erroneous errors

EDIT: affects any editor whose TS language server resolves a file against the nearest tsconfig.json (VS Code, Zed, nvim).

Looks good!

I missed this when switching us over to Vitest.

@akabiru we should be able to delete frontend/tsconfig.compodoc.json. It's not referenced anywhere.

Pull request overview

Adjusts the frontend TypeScript configuration to use a solution-style root tsconfig.json so editors/tsserver route *.spec.ts files to tsconfig.spec.json (with vitest/globals), avoiding phantom “Cannot find name 'describe'/'it'/'expect'” diagnostics.

Changes:

• Convert frontend/tsconfig.json to a solution-style root config (files: [] + references to app/spec projects).
• Broaden frontend/tsconfig.app.json include/exclude patterns to ensure non-spec files are owned by the app project while excluding *.spec.ts.
• Remove frontend/tsconfig.compodoc.json and delete an unused(?) global search tabs component file.
