fix: implement minor emui feedback tweaks

[Dartoxian]

Description:

A selection of smaller feedback items from the postdevconnect burndown:

• Fixed tab index onto the enclave configuration form to prevent default focus being on the close button
• Fixed destroy enclaves dialog closing early when multiple enclaves were destroyed
• Print the emui version on launch in the browser console
• Tooltips on enclave status and service status
• Updated file download names for artifacts and service arguments to include --
• Dynamically size the log viewer based on the window size (all css, no resize listeners).
