Complete validation and error handling items from todolist.md

[Copilot]

Completed 4 items from the project TODO list focused on directory datastore validation and error handling.

Changes

Validation for .webfile files

• translateFilesIntoWebfilesArray() now validates that .webfile format files have non-empty id and timestamp
• Validation skipped for image files (JPG/JPEG) which auto-populate these fields from EXIF
• Throws descriptive exceptions: "Webfile in file 'X' does not have a valid id/timestamp"

Auto-assignment in storeWebfile

• storeWebfile() auto-assigns uniqid() for missing id and time() for missing timestamp
• Forces .webfile extension regardless of input

Error handling improvements

• readFileAsWebfile() wraps unmarshalling errors with file context
• Validates content is non-empty before unmarshalling
• Try-catch blocks prevent cryptic errors from propagating

Test coverage

Added 4 unit tests validating:

• Exception thrown for missing id
• Exception thrown for missing timestamp
• Auto-assignment of id and timestamp
• Graceful handling of empty files

Example

Before:

$webfile = new MSampleWebfile();
$webfile->setFirstname('Test');
// Missing id and timestamp - would fail cryptically later
$datastore->storeWebfile($webfile);

After:

$webfile = new MSampleWebfile();
$webfile->setFirstname('Test');
// Auto-assigns id and timestamp, always saves as .webfile
$datastore->storeWebfile($webfile);

All directory datastore tests pass (9/9, 26 assertions).
