Fix overflowing/clipped UI text and give buttons a consistent flat style

Instruction and status labels used AutoSize/fixed widths with no wrap
constraint, so long Italian paragraphs and network paths ran past the
window edge or got clipped instead of wrapping. Report dialogs had
fixed-height labels that clipped multi-line text. ProgressForm's folder
label could overflow its non-resizable dialog.

- Labels now wrap responsively (TableLayoutPanel column at 100% + Dock=Top)
  instead of a fixed pixel cap, so they reflow when the window is resized.
- Report dialog labels switched from fixed Height to AutoSize.
- ProgressForm's folder label truncates with ellipsis + tooltip, matching
  the existing pattern used by the import status label.
- Added ApplicationHighDpiMode=PerMonitorV2 to fix control proportions on
  scaled displays.
- Added UiStile.cs: shared flat button style (primary/secondary), rounded
  corners for the wizard nav buttons, and AutoSize+padding on all buttons
  so button size always matches its text (fixes text getting clipped when
  a hardcoded Size was too narrow for the label).
- Fase 5's drag&drop .asm list now fills available vertical space instead
  of a fixed 680x160 box.
