IniFile::Find() used a static buffer to return results, causing bugs
when multiple Find() calls were made before using the first result.

Change Find() to return std::optional<std::string> instead of
std::optional<const char*>. Each caller now owns their result copy.

Core changes:
- Remove static buffer from Find(), return std::string by value
- Update all callers to use s->c_str() where const char* is needed
- Use string methods (.empty(), .length(), ==) instead of C functions

C API compatibility maintained via static storage in iniFind() wrapper.

No functional changes - all updates are behavior-preserving.

Follow-up to the C++ IniFile::Find() reentrancy fix. The previous
commit changed Find() to return std::string by value, but the C API
wrapper iniFind() still used static storage, making it non-reentrant.

Add iniFindString() that takes a caller-provided buffer, making it
safe for concurrent use and multiple sequential calls. Reimplement
iniFind() as a deprecated wrapper around iniFindString().

Migrate all C callers to iniFindString():
- mb2hal: 11 call sites
- vfdb_vfd: 2 call sites
- vfs11_vfd: 4 call sites
- halcmd: 2 call sites

Also clean up dead commented-out code in mb2hal and halrmt.
