v3.8.4: icon fix + release packaging

Version 3.8.4 (2026-03-28)

Added / Improvements

• Mapped resources/media/icon_*.png files to home menu items so the supplied icons are used for Favorites, Recently Watched, Account Info, Live TV, Movies VOD, Series, TV Guide, Catchup, Search, Settings, and Extras.
• Added icon_LAST_PLAYED.png and set it as the fallback for the Last Played home entry to ensure a reliable local icon.
• Set Extras to use a local icon_EXTRAS.png fallback to avoid blocked or unreachable remote assets.

Bug Fixes

• Fixed IndentationError: unexpected indent in default.py by normalizing ART PATHS and removing an unreachable nested try/except in livecategory().
• Ensured the Last Played home item always uses the local icon to avoid UI issues caused by unreachable icon hosts.
• Packaging: created clean release ZIP and published release v3.8.4 (excludes .venv, __pycache__, .git, and .pyc files).
