Changelog

Add ImportConnectionAsync method to the SDK IConnectionService interface,

allowing plugins to migrate existing refresh tokens to shell-level

connections during the transition from plugin-managed to shell-managed OAuth.

Expand ConnectionsViewModel with Google/Microsoft connection management:

ObservableCollection of OAuthConnectionItem for each provider, connect/disconnect

commands, scope summarization (Gmail, Calendar, Outlook). Add Google and Microsoft

sections to SettingsPanel.axaml with connected accounts list showing email, scope

summary, connected date, and disconnect button per account. Both sections support

multiple accounts with connecting state indicators.

Create OAuthProviderConfig with combined scopes (Gmail + Calendar + identity

for Google, Outlook IMAP/SMTP + identity for Microsoft). Create

OAuthBrowserFlowService consolidating the PKCE loopback flow from the Email

plugin into a reusable shell service. Expand ConnectionService with multi-account

support: ConnectOAuthAsync orchestrates the full flow, ImportConnectionAsync

enables migration from plugin-level tokens, GetAccessTokenByIdAsync auto-refreshes

expired tokens with per-connection SemaphoreSlim concurrency control,

GetConnectionsWithScopesAsync filters by required scopes. Register

OAuthBrowserFlowService in DI. Desktop version bumped to 1.46.0.

Add ConnectionId field to ConnectionInfo record and new multi-account

methods to IConnectionService: GetConnectionsAsync, GetConnectionByIdAsync,

GetAccessTokenByIdAsync, and GetConnectionsWithScopesAsync. Existing

single-connection methods remain unchanged for backward compatibility.

This enables Google/Microsoft OAuth connections to support multiple

accounts per provider. SDK version bumped to 1.46.0.

The calendar popup now inherits the width of the trigger button so

the dropdown looks uniform and aligned with the field it belongs to.
