fix(print): fix app-wide printing and remove a global print-CSS leak

Root cause of blank/clipped print output across the app: the document root
(html/body) is globally locked to one viewport height with overflow hidden,
and Angular Material's drawer/tab-body containers each add their own
on-screen scroll clip on top of that. main.scss now frees the full chain for
print (document root, CDK drawer/sidenav containers, mat-tab-body, and the
account-view's mat-tab-nav-bar which was rendering as a stray grey scrollable
strip since it isn't covered by the mat-tab-group header rule already hidden).

Also fixed both certificate print dialogs (share-certificate-dialog,
deposit-certificate-dialog) reusing a `::ng-deep body > :not(.cdk-overlay-
container)` rule to hide the shell during their own print: under Angular's
style encapsulation this style is emitted fully unscoped into the global
stylesheet and is never removed once the component has loaded once in a
session, silently blanking every other page's print output for the rest of
the session. Dropped `::ng-deep` from that one selector so it goes back to
being properly scoped (and therefore inert, matching the other two dialogs
that never had this bug) — the app shell is already hidden for every print
via the global main.scss rules, so no dialog needs its own global override.
