feat: add tui interactive interface to work with llm translation

[josix]

This pull request introduces a new interactive translation application using the textual framework and integrates Google Generative AI for translation tasks. It also includes updates to the dependencies in the pyproject.toml file.

New interactive translation application:

• .scripts/interactive_translate/main.py: Added a new TranslationApp class using the textual framework to provide an interactive UI for translating PO files. The application supports navigation through entries, accepting translations, generating translations using Google Generative AI, and saving changes.

Dependency updates:

• .scripts/pyproject.toml: Added new dependencies textual, powrap, and google-generativeai to support the new translation application.

	def main(po_file_path: str):
	app = TranslationApp(Path(po_file_path))
	app.run()
	if __name__ == "__main__":
	import sys
	if len(sys.argv) > 1:
	main(sys.argv[1])
	else:
	print("Please provide a PO file path")
	def main(po_file_path: str):
	app = TranslationApp(po_file_path)
	app.run()
	if __name__ == "__main__":
	import argparse
	desc = 'TUI for LLM translations'
	parser = argparse.ArgumentParser(description=desc)
	parser.add_argument('po_file_path', type=Path,
	help='Path to the PO file to translate')
	args = parser.parse_args()
	main(args.po_file_path)

What about using argparse instead of sys.argv?

There's a missing space at the end of the first line that causes Chinesefor to be merged together. While I was at it I made the spacing of the other lines consistent, by moving all the spaces at the end of the sentences.

	self.notify(f"Error: {str(e)}", severity="error")
	self.notify(f"Error: {e}", severity="error")

The str() is not necessary here.

This has the same bug (Chinesefor) as the other prompt. Since it looks duplicated, it might be better to factor it out, and reusing it in both places instead.

Close it since I believe the newest Copilot Agent translation flow will be more user-friendly.
