When bclock.conf has an empty bitcoincli path, catch the PermissionError
and redirect to introINIT() with a helpful error message instead of
crashing with 'Fatal error: Permission denied'.

Features:
- Persistent status bar with mode, block height, BTC price
- Side panel showing live fee estimates (fast/medium/slow)
- Keyboard navigation (A=PyBLOCK, B=Bitcoin, L=Lightning, etc.)
- Auto-refresh every 30 seconds via async workers
- Dark theme with Bitcoin-inspired color scheme
- CSS-based responsive layout

Replace ANSI escape code menus with Rich-styled components:
- PyBlock.py MainMenu(): Rich status bar, header panel with node info,
table-based menu with colored keys
- SPV/spvblock.py MainMenuCROPPED(): same Rich integration
- Use rich_prompt() for styled input
The main menu now renders with bordered panels, consistent styling,
and proper terminal-width adaptation via Rich.

When users type an unrecognized option, they now see a yellow
"Invalid option 'X'. Try again." message instead of silent no-op.
Applied to:
- PyBlock.py mainmenuControl() and bitcoincoremenuLocalControl()
- SPV/spvblock.py mainmenuLOCALcontrol()

Add show_error(str(e)) before every logger.debug() call so users see
a red error message when operations fail, instead of silent failures:
- PyBlock.py: 31 instances of "Suppressed error" pattern
- SPV/spvblock.py: 186 instances of "spvblock" error pattern
Users now see "! Error: <message>" in red text before being returned
to the menu, while errors still log to pyblock.log for debugging.

- PyBlock.py MainMenu(): fetch BTC price from mempool.space API,
display status_bar() showing mode/block/price before menu header
- SPV/spvblock.py MainMenuCROPPED(): same status_bar integration
- Import shared.ui utilities in both files
The status bar shows at a glance: active mode (Local/Remote/Lite),
current block height, and USD price of Bitcoin.

Replace cd-and-run shell patterns with list-based subprocess.run()
using cwd parameter for directory context:
- Phoenix macOS ARM installer
- Luxor CLI help
- Mempool CLI (2 instances)
- SatSale, Cashu, Warden, bpytop launchers
- Bija docker-compose
- Both SPV/spvblock.py and PyBlock.py

Replace all uses of 'list' as a variable name for shell command strings
with 'cmd' to avoid shadowing Python's built-in list type.
Affects ppi.py, PyBlock.py, SPV/ppi.py, and SPV/spvblock.py.

- PyBlock.py: Replace 14 star imports with explicit named imports,
remove unused `from art import *` and `from SPV.spvblock import *`
- ppi.py: Replace star imports, remove unused art/nodeconnection imports,
remove duplicate `import requests` and dead lnpay_py comments
- nodeconnection.py: Replace star imports, remove unused art import
This improves code clarity, prevents namespace pollution, and makes
dependencies between modules explicit and traceable.

Replace params=[] with params=None pattern to prevent shared state
between calls. Affects PyBlock.py, nodeconnection.py,
SPV/nodeconnection.py, and clockscriptREMOTE.py.

Major improvements across 7 areas:
- Add centralized Config singleton (config.py) replacing ~176 config
reloads per session with a single cached load
- Add logging framework (log.py) with RotatingFileHandler, replacing
silent except Exception: pass blocks with structured logging
- Refactor menu system (menu.py) with data-driven color selection,
eliminating ~1,370 lines of duplicate menu functions
- Create shared/ modules extracting 7 utility functions duplicated
between PyBlock.py and SPV/spvblock.py
- Clean dependencies: pin all versions, remove stdlib packages
(asyncio, threading), remove unused imports
- Improve Docker: pin ubuntu:24.04, add non-root user, use venv
- Improve CI: update to actions v4/v5, add test job before publish
- Fix entry point: wrap main loop in def main(), proper module import
