fix(letter-mgmt): make share certificate bank identity dynamic and fix broken printing

- Certificate PDFs, the preview dialog, and both share-certificate list views
  (demo + live) now pull bank name/address/reg no/seal text from the
  Institution Profile instead of a hardcoded "Nexora" identity.
- Certificate preview dialog print CSS was clipped to the dialog's on-screen
  scroll viewport (maxHeight config); switched to position:fixed + unclipped
  overlay ancestors so the full certificate prints, not just a border sliver.
- Global print stylesheet now also hides the app shell's real 2-row nav menu
  (.main-header/.kpi-ticker, not routed through <mifosx-toolbar>) and frees
  the CDK sidenav/tab-body scroll clipping, so printing any page no longer
  captures the nav chrome or gets cut off to one screen's height.
