RustBox 0.0.3

RustBox 0.0.3 is a mobile UI and appearance-focused maintenance release.

Highlights

Mobile settings and dialogs no longer grow wider than the viewport; source, header and calendar cards fill their dialog without transparent side strips.
Calendar controls wrap into a touch-friendly grid on narrow screens.
The visual Sieve editor keeps checkboxes next to their labels and switches complex rule rows to one column on mobile.
Message recipient details can be expanded by tap or keyboard to reveal full addresses.
IMAP storage quota is visible in the main folder sidebar above the IMAP/version footer.
default_theme = "system" | "dark" | "light" controls the global pre-login/login theme from TOML.
New interface profiles: Gmail inspired, Proton inspired, Zoho inspired, Outlook inspired and Minimal.
Polish localization now covers substantially more settings, dialogs, filters, calendar and contact UI.
