ColdCore was non-functional due to literal '$HOME' paths that never
expanded, making all file checks always fail. The upstream project
(jamesob/coldcore) is experimental/alpha and requires Coldcard
hardware, limiting its audience.
Removed: callColdCore() function, menu entry "I" (ColdCore), and
handlers from PyBlock.py, SPV/spvblock.py, and umbrel-app.yml.
