When a project is opened through a symlinked path, libgit2's
git_repository_workdir() returns the canonical path with symlinks
resolved. This caused a path mismatch between the tree cache
(which uses the user-provided symlinked path) and git status
results (which used canonical paths), preventing status icons
from being displayed.
The fix introduces SetProjectDir()/GetProjectDir() methods to
KIGIT_COMMON to store and use the user-provided project path.
A helper function computeSymlinkPreservingWorkDir() computes
the git working directory path while preserving symlinks from
the original user path.

Updates the git connection dialog to reflect default agentic behavior,
followed by default keys and only then reverting to a custom selection
if the user desires

- Utilize scoped deletion for individual git_*_free() calls
- Protect against multiple usage when updating icons
- Reduce frequency of git update calls
Don't keep passwords in plain text config files that may be checked into
version control. Passwords stored in system-specific password managers

Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
