(feat) add Kanban status actions to card detail and overflow menu

[reniko]

What

Adds additional ways to change a Kanban card's status:

1. Status field in the card detail/edit modal.
2. Status action in the card overflow menu (...) on both mobile and desktop.
3. User setting to hide the always-visible mobile status dropdown on Kanban cards.

Also makes the property groups in the card detail modal collapsible. Metadata starts collapsed, while the editable property groups start expanded.

Why

Desktop users can already change status via drag & drop, but mobile drag & drop is less practical. The existing mobile on-card dropdown works, but takes card space. This adds a compact overflow-menu path while keeping the existing dropdown visible by default for backwards-compatible behavior.

The detail modal was also inconsistent: fields like priority, score, reminder, target date, and estimated time were editable, but status was not.

Reused / not changed

• Reuses the existing updateItemStatus server action.
• autoComplete remains handled centrally in updateItemStatus.
• No changes to the YAML status data model (id, label, color, order, autoComplete).
• Desktop drag & drop behavior is unchanged.
• The existing hideStatusOnCards setting remains separate from the new mobile dropdown setting.

Details

• The new setting is hideMobileStatusDropdown.
• Default is "disable", meaning the mobile dropdown remains visible for existing and new users.
• hideStatusOnCards still only controls the compact status label on cards.
• hideMobileStatusDropdown only controls the always-visible mobile status dropdown.
• The overflow-menu Status ändern / Change status action remains available even when the mobile dropdown is hidden.

autoComplete behavior

Handled centrally in the existing updateItemStatus server action, so status changes from drag & drop, the mobile card dropdown, the overflow-menu status modal, and the detail modal all share the same completion behavior.

Mobile context menu variant

Implemented via the existing card overflow menu (...). Selecting Change status opens the existing Modal component, which behaves as a bottom sheet on mobile and a regular modal on desktop.

Translations

• en and de updated manually.
• Other existing locale files updated with machine translations; review welcome.

Testing

Validated with:

• yarn tsc --noEmit
• yarn lint

Manually checked:

• Status change in card detail modal keeps the modal open.
• Metadata section starts collapsed.
• Editable property groups are collapsible.
• Mobile status dropdown can be hidden via the new setting.
• Overflow-menu status change works on mobile and desktop.

Hey, unfortunately something happened where the modal is not horizontally scrollable anymore.

This means anything out of the modal viewport horizontally is unusable!

Sorted it out, happy to merge if you are ok with it ❤️
