feat(update): introduce modern update system with JSON changelog, reminders and checksum validation

- Replace legacy AutoUpdater dialog with a custom update UI integrated into the application theme - Add support for JSON-based changelog with HTML fallback for backward compatibility - Implement "Remind later" and "Skip version" options to reduce intrusive update prompts - Add visual update indicator and manual "Check for updates" action in the links menu - Persist user update preferences (skipped versions and reminder delays) - Introduce checksum validation (SHA256) for downloaded update packages - Migrate changelog source format from HTML to JSON - Automatically generate HTML changelog and GitHub release notes from JSON via CI - Consolidate release automation into a single GitHub Actions workflow - Remove obsolete legacy update dialog and related code - Expand localization coverage for update-related UI
fix(confirmations): roll back the erroneously assigned ConfirmCommand in PurchaseConfirmation

bohdanbtw	69589075e5	feat(import): support SDA-encrypted mafiles (#17 ) NebulaAuth previously supported only plain JSON `.mafile` files. Steam Desktop Authenticator (SDA) can encrypt these files and stores per-file salt and IV values in `manifest.json`, which prevented users from importing accounts protected with SDA encryption. Add support for importing SDA-encrypted mafiles. The importer now detects encrypted blobs, automatically locates the SDA manifest, prompts for the SDA password once, and decrypts files during import. The import flow was also refactored to unify handling of plain and encrypted mafiles. SDA detection and decryption logic is moved into a dedicated helper, batch imports reuse the entered password, and the ViewModel import logic was simplified with explicit result handling instead of exception-driven control flow. This allows users to migrate accounts from Steam Desktop Authenticator to NebulaAuth even when their mafiles are encrypted.	2026-03-12 21:22:18 +02:00
bohdanbtw	4b547e19c4	feat(confirmations): reveal items in grouped market sell confirmations (#18 ) Grouped market sell confirmations previously appeared as a single row showing only the item count (e.g. "Sell 4 pcs"). This made it difficult to verify which items were being confirmed or their prices. Add an expandable grouped confirmation that reveals individual items with their icon, name and price. Also allow confirming or canceling items individually while keeping confirm-all and cancel-all actions. Includes a scrollable list for large batches and minor UI/code cleanup.
