Add investments to All tab, withdrawal on create, modal fixes, and login logo

- Show investment subtable under All accounts tab (was only under Operating/Reserve)
- Add "Withdraw from primary account" switch (on by default) when creating
  investments; creates a journal entry to credit the primary asset account
  and debit the equity offset, keeping the books balanced
- Prevent all account modals from closing on outside click to avoid data loss
- Replace login page text title with the SVG logo
