Split modals into separate component

[imnasnainaec]

Suggested refactor for #33

This is what it might look like to have the models handled in their own component. The only change in behavior is that after a project is created via the select-project modal, you don't return to that modal, which I think would be simpler for users anyway.

Note: the tests haven't been updated to match this change.
Also: some of the cross-component types should perhaps be extracted to a common types file.
Devin has a few useful flags as well if this goes through: https://app.devin.ai/review/sillsdev/interlinearizer-extension/pull/62

📝 Walkthrough

Walkthrough

The PR refactors project modal state management by extracting modal UI orchestration from InterlinearizerLoader into a new ProjectModals component. Type contracts for modal state and persisted active project are defined in ProjectModals and SelectInterlinearProjectModal. The loader is simplified to delegate all modal logic to ProjectModals.

Changes

Modal State Extraction and Delegation

Layer / File(s)	Summary
Modal State Type Contracts src/components/SelectInterlinearProjectModal.tsx, src/components/ProjectModals.tsx	ActiveProjectState type captures the persisted subset of project fields from InterlinearProjectSummary. ModalState union type ('none' | 'select' | 'create' | 'metadata') defines visible modal states.
ProjectModals Component Implementation src/components/ProjectModals.tsx	ProjectModals orchestrates modal visibility, persists activeProject in WebView state, maintains local UI state for metadata project and origin tracking, syncs metadataProject from activeProject when entering metadata mode, and provides memoized callbacks for opening metadata, saving changes (merging into activeProject when applicable), and deleting projects. Conditionally renders SelectInterlinearProjectModal, CreateProjectModal, and ProjectMetadataModal based on modal state.
InterlinearizerLoader Refactoring src/components/InterlinearizerLoader.tsx	Imports ProjectModals and ModalState, converts activeProject handling from getter/setter to read-only snapshot, simplifies command handler to toggle modal state to create or metadata (gating metadata on activeProject existence), and removes inline modal rendering, callbacks (handleViewInfo, project-created/saved/deleted flows, metadata source tracking), and state setters (setMetadataProject, resetActiveProject). Renders single ProjectModals component with modal, projectId, setModal, and useWebViewState.

🐰 Modal state hops from loader to home,
ProjectModals now has the throne,
Callbacks and handlers find their way,
Simpler paths to save the day,
State refactored, clean and neat! ✨

Add @returns to the JSDoc block for consistency.

The coding guidelines require @returns for all functions except those returning void or Promise<void>. React components return JSX.Element, so should include this tag. The similar component SelectInterlinearProjectModal in SelectInterlinearProjectModal.tsx (line 59) includes @returns, so adding it here maintains consistency across the codebase.

📝 Suggested JSDoc addition

  * `@param` props.useWebViewState - Hook for reading and writing values persisted in the WebView's
  *   saved state (survives tab restores)
+ * `@returns` A container that conditionally renders one of the project modals (select, create, or
+ *   metadata) based on the current modal state, or an empty div when no modal is open.
  */
 export default function ProjectModals({

As per coding guidelines: "Every function and method—exported or internal—must have a JSDoc block with a summary sentence describing what the function does and why it exists, @param for every parameter, @returns describing the return value (omit only for void/Promise<void>)".

Somehow I didn't quite catch what you meant when you made the earlier comment. This looks great; thanks for doing it. I will make some adjustments and get it tested properly.
