Esc menu without "Exportieren"; export screen mod removed

- cUI_EscMenu::BuildLines hook: the UI_ESC_EXPORT line is removed, the
  lines below move up, the window shrinks by one line, centred.
- game/ui/control.h: control vector helpers (ControlsIn, RemoveControl,
  SetControlAt, DeleteControl, ControlNamed), used by the main menu too.
- The export screen is unreachable now: charexport.cpp and
  docs/char-export.md deleted. Spielen screen redesign noted in todo.md.

-# Character export screen (`src/mods/charexport.cpp`)
-
-Request (2026-10-18): the export screen (Esc menu "Exportieren") was not
-adapted to widescreen (layout and clicks shifted), slots could not be
-cleared or overwritten; the screen and the save game window need black
-beside the background picture.
-
-## Layout
-
-See `hud.md`, "Full-screen windows": the 3D scene was stretched across the
-wide viewport; the window now draws with a viewport on the centred frame.
-
-## cUI_Character
-
-One window for the main menu's character selection / import and the export
-screen (vtable 0x894fa8, render vf44 0x70f160, events vf10 0x70e860).

-| Field | Meaning |
-|---|---|
-| +0x390 | mode: 4 selection, 5 export, 6 overwrite confirmation (7 import) |
-| +0x394 | previous mode |
-| +0x1b4 | 8 slot controls; hero id at +0x2f8 (0: empty) |
-| +0x1d6 | selected slot (char, -1 none) |
-| +0x3b4 | erase button ("UI_CHAR_ERASE_TOOLTIP") |
-
-| Address | Function |
-|---|---|
-| 0x70c760 | SetMode (mode), ret 4; entering mode 5 reloads the heroes |
-| 0x70c440 | SelectSlot (char slot), ret 4; shows the erase button in modes 4 / 7 only |
-| 0x70d0f0 | ExecuteAction (action, slot, extra), ret 0xc: 6 export into slot (`Save\Hero%.2d.pax`), 9 export with confirmation if occupied |
-| 0x70e650 | right-hand button: in mode 5 action 6 (empty slot) or 9 (occupied) |
-| 0x7f01a0 | HeroSlots_DeleteHero (slot + 1), thiscall on 0x7d7c40(), ret 4 |
-
-## Overwrite
-
-Measured with a log: exporting to an occupied slot was already the game's own
-path (action 9 -> mode 6 confirmation -> action 6). It only failed because
-clicks hit the wrong place before the layout fix.
-
-## Clear
-
-The erase button is created for every mode, and its click handler (vf10)
-does not check the mode: it opens the game's confirmation
-(UI_CHAR_ERASE_CONFIRM, cUI_BusyDlg), whose answer (0x72087b) calls
-DeleteHero. The mod shows the button in export mode whenever an occupied slot
-is selected (after SetMode / SelectSlot). After DeleteHero, if the screen is
-in export mode, it enters export mode again (reloads the heroes) and clears
-the selection; otherwise the erased hero stayed until the next export.

+black sides, hud.cpp FrameScope).
