Keep user config out of the install dir; frameless window with working resize

Three related fixes after the notes feature landed:

Config location: build_and_deploy.ps1 wipes its target directory before
every deploy, and app_dir() had just been pointed at that same directory
-- so every rebuild silently deleted the user's config and the app
rebuilt it empty from the board, losing all notes. Config now lives in
%APPDATA%\VersaPadViewer (roaming), separate from the install dir, and
the build script additionally rescues any versapad_config*.json it finds
in the target so legacy installs survive an upgrade.

Window chrome: hide the title bar (plain Tk overrideredirect, no ctypes
window manipulation) and move the mode checkboxes up next to the title,
which reclaims two full rows of header height that the taller note cards
had eaten. Removing the title bar also removes the resize borders, so
add a grip -- anchored with place() to the window corner rather than
packed after the content, which would push it out of view exactly when
the window is too small and the grip is needed. Default geometry grown
to fit the taller cards, and empty encoder note lines are no longer
rendered at all.

Note truncation: the note area was a fixed 34px and cut longer notes
mid-word; it now takes the remaining card height.
