A new overview, and enterprise sign-on

New

• A completely new company overview. The screen most users open first, rebuilt.
• SSO via OIDC, with Fidal as a provider — enterprise sign-on for large firms.
• A formalities table on the company overview, including filing deposits and annual accounts.
• Expressions arrive in drafting, and conditions can now be nested inside conditions.
• A confidentiality request template as a quick action.
• RMT Chatbot 1.5.

Improved

• The share ledger transaction table is virtualized — large ledgers scroll smoothly.
• Duplicate persons are prevented at creation.
• Drag and drop works across the whole folder, not just the dropzone.
• Optional and array type modifiers for variables.
• Certificate generation fixed for off-chain registers.
