fix: side peek des bases repasse en vanilla JS + largeur 1100px standard (v7.49.0)

- Panneau peek: les bindings Alpine (x-data absent du conteneur) rendaient
  loovverture et le redimensionnement inoperants -> cblage direct sur le document.
- Helper unique window.fdWirePeekResize (app.js): pointer capture, 300px-90vw,
  clic=fermer, largeur persiste fd_peek_width partagee entre les 4 peeks.
- database-table-container margin:0 (tableau colle a gauche, marge Library).
- .lib-container remonte dans app.css (trash etait pleine largeur), .db-index 1100px.
- ObsiGate verifie sans code: creation .xlsx OK (openpyxl, #186).
