feat: Ephemeral DB mode & CLI integration tests

[matheus23]

Main addition: Integration tests between the CLI and server in fission-cli/tests/main.rs. Also:

• Add --ephemeral-db parameter to the server to use an ephemeral DB while running which is destroyed on close
• Add --close-on-stdin-close parameter to the server to enable listening on EOF in stdin and closing appropriately
• Add --gen-key-if-needed parameter to the server to enable writing a new key to the fs if there is none yet
• Added --no-colors CLI parameter to turn of colored output
• Added hidden --key-seed CLI parameter to enable isolating CLI tests
• Refactor server tests a bit. More ? and less &, TestContext::request shorthand, etc.

Had to disable doctest compilation due to https://github.com/rust-lang/rust/issues/95825. We don't have any doctests anyways, so it doesn't really matter. We just need to remember to reenable once we have (and fix the issues).
