fix(studio): readable logs + in-app config.yaml viewer

Browse source 
- Strip ANSI / control characters when reading log files so daemon
  logs that carry colour escape codes render clean instead of as
  garbled special characters (the source side is fixed in the hub
  too; this is the defensive belt for existing files).
- Generalise the file viewer (read top-down + plain mode) and add an
  in-Studio "View" affordance for config.yaml / .yml / .toml on the
  Doctor paths panel, so config is readable without leaving Studio.
