calendarium@kami911: timezone fixes, auto-detected location, customizable border, French Republican calendar

[KAMI911]

Summary

Alternate calendars

• Add French Republican calendar (equinox-based) as an option under Alternate Calendars — each Republican year begins at the true autumnal equinox, so the 5/6 intercalary days fall out naturally instead of from a fixed leap-year formula

Location & timezone

• Fix geocoder lookups to save the canonical city name back to the city name field
• Fix primary-location sunrise/sunset and moonrise/moonset times being rendered in the computer's timezone even when the location is elsewhere: add a primary-tz IANA timezone setting, auto-filled by the city search alongside latitude/longitude (empty = use the system timezone)
• When "Use manual location" is off, detect the location automatically from the computer's system IANA timezone (resolved asynchronously via GLib.TimeZone, /etc/timezone or the /etc/localtime symlink, then looked up in tzdata's zone1970.tab/zone.tab), instead of hard-coding Budapest — Budapest remains the fallback
• Add an optional "Show the clock and date in the primary location's timezone" toggle (off by default); when on, the main clock, date, month name and date-based calendar sections follow the primary location's timezone instead of the computer's

Appearance

• Add an optional customizable border around the desklet: toggle, width 1–10 px, color, and corner radius 0–40 px; off by default
• Move the Appearance settings (icon size, text scale, background opacity, border) onto their own settings page

Zodiac icons

• Change the Metal element symbol to a shield (U+1F6E1) for better readability
• Use a locale-aware globe emoji (🌍/🌎/🌏) for the Earth element based on the system locale

Translations

• Clean up leftover merge markers and duplicated text in the Hungarian (hu.po) translation
• Add English (.pot) and Hungarian strings for the new settings
