Add import notes feature to settings page

[Copilot]

Adds an "Import Notes" section to the plugin settings page (before Export) that lets users select multiple files via a file chooser dialog, copies them into the configured notes directory, and registers them in the note storage.

Changes

• ImportNotesService — Reads selected files and copies them to the notes directory via FileHelper.createFileWithContent. Resolves duplicate filenames by appending a counter (note (1).md).
• NotesConfigImportNotesPanelComponent — Settings UI panel mirroring the export panel pattern: title, description, import button with JFileChooser (multi-select, files only). Registers imported notes in NoteStorageRepository and shows success/error messages.
• NotesConfigFormComponent — Wired import panel between "Open folder" and "Export" sections.
• MyBundle.properties — Added 6 i18n keys for import UI strings.
• ImportNotesServiceTest — 5 tests: happy path, missing files skipped, empty input, duplicate name resolution, target directory auto-creation.

Design notes

ImportNotesService is kept free of IntelliJ platform dependencies (like ExportNotesService), making it directly unit-testable. Platform integration (settings lookup, repository registration) lives in the UI component.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
