### System details

 Omarchy: 4.0.0.r1046.gd570d99-1 (Quattro)   CPU: Intel Core i3-4030U @ 1.90 GHz   GPU: Intel Haswell-ULT Integrated Graphics   System locale: LANG=es_MX.UTF-8   Keyboard layout: US

### What's wrong?

<img width="1366" height="768" alt="Image" src="https://github.com/user-attachments/assets/1601c864-3486-48bf-bc6f-2c3aff1e535b" />

  I am testing Omarchy Quattro and noticed that the `omarchy.clock`
  widget does not follow the system locale for weekday and month names.

  After changing the system locale from `en_US.UTF-8` to
  `es_MX.UTF-8`, the rest of the system switched to Spanish correctly.
  The clock accepted a 12-hour format, but weekday and month names
  produced by `dddd` and `MMMM` are still displayed in English.

  ### Steps to reproduce

  1. Generate the `es_MX.UTF-8` locale.
  2. Set the system locale to `LANG=es_MX.UTF-8`.
  3. Log out or reboot.
  4. Configure the `omarchy.clock` entry in
     `~/.config/omarchy/shell.json` with a format containing `dddd`
     or `MMMM`.
  5. Observe the weekday or month displayed by the clock.

  Example formats:

  ```text
  dddd h:mm AP
  d MMMM 'W'ww yyyy
  ```

  ### Actual behavior

  The system and supported applications use Spanish, but the clock
  continues to display weekday and month names in English.

  ### Expected behavior

  The clock should use the current system locale, so `dddd` and `MMMM`
  display Spanish weekday and month names when the locale is
  `es_MX.UTF-8`.

  ### Relevant implementation detail

  At the time of testing, `Clock.qml` formats the value with:

  ```qml
  Qt.formatDateTime(
    date,
    activeFormat.replace(/ww/g, isoWeekLiteral(date))
  )
  ```

  Using an explicit locale appears to produce locale-aware formatting:

  ```qml
  Qt.locale().toString(
    date,
    activeFormat.replace(/ww/g, isoWeekLiteral(date))
  )
  ```
