refactor(system-utils): major refactoring / adding tests

Theme:
Modularize system-utilities into separate modules.
Clean up any typos, buts, and unused variables.
Add some initial ERT tests for new modules created.

Changes:
- Extract file handling into its own module (file-config)
- Extract keyboard macro management into its own module (keyboard-macros)
- Extract buffer burying (instead of killing) into its own module (undead-buffers)
- Extract all date/time config into its own module (chrono-tools)
- Moved keybinding discovery functionality and help into keybindings module
- Combine flyspell and abbrev (spell-check and autocorrect) to flyspell-and-abbrev.el
- Rename epa-config.el to auth-config.el for auth-source and epa settings.
- Refactor `cj/kill-other-window` for more accurate buffer handling.
- Include "*ert*" in the default bury (don't kill) list as killing it kills test runs.
- Bind C-c M-m to inhibit-mouse-mode
- Remove the unused ledger-file variable in user-constants.el.
- Removed obsolete C-x x m, C-x x r, and C-x x d key mappings.
- C-; b r to call cj/rename-buffer-and-file instead of typo’d function
- Other purely cosmetic comment changes to system-utils.el
ERT tests:
- Rename ERT test definitions to include module scopes (file-config, keyboard-macros)
- Add an ERT test for the timer bell's existence.
- Add ERT tests to cover `cj/kill-buffer-or-bury-alive`, prefix-arg behavior, window-killing commands, and bulk operations.
- Add test `authinfo-file` exists Missing authinfo triggers a debug message
- Add test that `gpg2` executable is on the user’s PATH
- Remove outdated authinfo test.
- Add “Run these tests” note where missing.
