feat: TUI logs view (#3064)

* fix: add logs page to TUI

* chore: print panic traces to TUI logs

* chore: stop and start tui nicely and a bit of refactoring

* chore: rustfmt

* chore: typo

* chore: use sync_channel for logs

* chore: don't try to unwrap err on try_send log message

* chore: fix compiler/lint warnings

* fix: Only create logs channel if TUI is enabled and resovle other small review comments

* fix: wrap logs in TUI to fix window size

* fix: debug and trace logs appear white in the TUI logs
