fix: smooth GUI during pipeline downloads and harden wizard connection test

Browse Source 
GUI log batching (_poll_log now drains queue into a single CTkTextbox.insert
call per 80 ms tick instead of N calls, each with see("end") scroll).

_QueueWriter strips ANSI/CSI escape codes and bare \r before enqueuing so
tqdm progress output is legible in the log textbox. OSC sequences terminated
by both BEL (\x07) and ST (\x1b\) are handled.

Wizard "Test Connection" moved off the main thread: requests.get runs in a
daemon thread; result posted back via after(0, ...). Widget refs captured
before thread launch to prevent stale updates if user navigates away. Bare
except narrowed to TclError (destroyed-widget guard only).

Code quality: import os moved to module level in app.py; _read_raw_config()
helper extracted to deduplicate dual raw config.json reads; return type
annotations added to _get_view_class, _get_dashboard, and cfg property.

Tests: 11 new unit tests for _QueueWriter (RED -> GREEN on OSC-ST fix).
