enhancement: redesign the virtual keyboard layout after the PS5 structural model #41

Summary

Rework the layout and visuals of the existing VirtualKeyboard to follow the PS5 keyboard's structural and interaction model, with ControlFS's own visual identity. Not a rewrite of the keyboard logic.

Motivation

The current keyboard works but its layout is dense and its function keys are scattered; a familiar console structure is faster to use from the couch.

Requirements

• Text field on top; four character rows (e.g. 1 2 3 4 5 6 7 8 9 0 @, Q W E R T Y U I O P #, A S D F G H J K L " /, Z X C V B N M . _ ? !).
• Function row: ⇧ (Shift) · ABC (letters) · @#: (symbols) · wide SPACE · ⌫ (Backspace).
• Bottom row: cursor ◀ ▶ (and ▲▼ where multi-line applies) · … (more: accents, language) · wide DONE.
• Shift: one tap = next letter uppercase; two taps = Caps Lock (behavior already exists in ShiftState).
• Keep PT-BR and EN layouts, uppercase/lowercase, numbers, symbols and accents (accents via the … page or long-press).
• Field-type rules preserved (file names disable forbidden characters; paths allow separators; passwords masked).
• Uses ControlFS theme tokens; no Sony assets, logos, textures or screenshots.
• Shared by every text field: create folder, rename, search, archive password, compress name, filters, batch rename, path edit.

Controller UX

D-pad/left stick move focus; South/A (✕) types the focused key; East/B (○) cancels; West/X (□) Backspace; North/Y (△) Shift; LB/RB move the cursor; Start/Options = Done; View/Create toggles symbols. Prompts come from #34.

Technical Notes

Change VirtualKeyboardLayouts.Build and ModalView.BuildKeyboard; keep VirtualKeyboard (model) and its tests; adjust KeyboardDriver test helper to the new grid.

Acceptance Criteria

• All existing keyboard tests pass after updating the layout-dependent helpers.
• A user can type Relatório ação 2026 (an accented Portuguese sample) using only the D-pad and South.
• Layout matches the structure above at 1080p and on a handheld.

Testing

Unit tests for new branches and for every bug reproduced before a fix (no trivial variations, see AGENTS.md). Manual comparison of flows (not visuals) with a PS5 keyboard; screenshots in smoke.

Dependencies

• Depends on feat: add dynamic controller button prompts to action bar #34 — feat: add dynamic controller button prompts to action bar
