Replace UA logo

[gtsiolis]

Description

This will replace the UA logo and add a message in the bottom right corner of the loading screen (workspace start).

• The placement is due to the already packed elements stacked vertically in the middle of the screen, which would cause the message to disappear on smaller viewports.
• The style was changed to be more subtle so that it's not conflicting with the existing information architecture and hierarchy of the workspace start page.
• Instead of the 🇺🇦 flag emoji, a subtle and generic custom SVG icon was used with the colors of the 🇺🇦 flag emoji, inspired from the dashboard status indicator for workspaces, integrations, and more.
