test(studio): seven FaiLog cases + visibleForTesting path override
Some checks failed
Security / Security check (push) Failing after 1s
Details

Browse source 
FaiLog used to compute its destination directly from HOME, which
made it impossible to test without scribbling on the operator's
real ~/.fai/logs/. Adds a static testPathOverride seam tagged
@visibleForTesting so the singleton can be redirected at a per-
test temp file.

The new test/fai_log_test.dart covers:

  - append() writes one JSON-shaped line per event
  - context field round-trips when supplied
  - tail() returns oldest-first
  - tail(maxLines:) caps and keeps the newest entries
  - rotation moves the previous log to .log.1 past 256 KiB
  - path getter honours the override
  - writes to an impossible path do not throw — best-effort
    contract that protects the UI from log-write failures

Production behaviour is unchanged: when the override is null
the path getter still computes from HOME/USERPROFILE.
