fix(portal): align right column top with sidebar top

Odoo's portal_layout wraps page content in <div class="container pt-3 pb-5">.
The pt-3 (1rem) was pushing the right column's first visible content ~16px
below the sidebar card's top edge, so the two column corners looked
misaligned. Zero out the top padding on that inner container, scoped via
.o_fp_portal_main #wrap > .container so it only applies inside our shell.
