feat: Expand maps button

[bijx]

Description:

QoL fix w.r.t. "All" maps category. Maps used to all be shown in a big list, now the category sections need to be expanded one by one. Categories are super clean and useful, but to visually see and pick maps when you're not certain which one you want to play becomes challenging (to click and expand each category manually). This just adds a simple "Expand All" and "Collapse All" button to the all category list on Solo and Private Match screens.

Please complete the following:

• I have added screenshots for all UI updates
• I process any text displayed to the user through translateText() and I've added it to the en.json file
• I have added relevant tests to the test directory

Walkthrough

MapPicker adds a new allCategories getter and toggleExpandAll() method to manage expand/collapse state. The renderExpandToggle() uses these, and render() restructures the tab area to show the toggle only on the "all" tab. Two i18n keys are added.

Changes

MapPicker Expand/Collapse All

Layer / File(s)	Summary
allCategories getter, toggleExpandAll, and i18n keys src/client/components/map/MapPicker.ts, resources/lang/en.json	New allCategories getter returns mapCategoryOrder without "featured". New toggleExpandAll() sets expandedCategories to either empty or full set. Two new translation keys collapse_all and expand_all are added.
renderExpandToggle and render() tab area update src/client/components/map/MapPicker.ts	renderExpandToggle() now maps over this.allCategories and calls toggleExpandAll(). The render() tab area wraps the tablist in a flex row and shows the expand toggle only when activeTab === "all".

Poem

📂 All open, all shut—just one little tap,
Categories fold neatly or fill every gap.
allCategories gathered, no "featured" in sight,
A toggle that flips with clean TypeScript delight.
Expand, collapse, compose—keep the logic tight! ✨

In `@src/client/components/map/MapPicker.ts`:
- Around line 78-83: The toggleExpandAll logic in MapPicker is treating any
non-empty expandedCategories Set as “all expanded,” so a partially expanded
state collapses instead of expanding the remaining categories. Update
toggleExpandAll and the related label/rendering logic to compare
expandedCategories.size against allCategories.length, and only collapse when
every category is expanded; otherwise expand all remaining categories.
