Implement winner absence functionality and improve container management

[svg153]

This pull request introduces functionality to handle absent winners in a raffle application, enhancing the user experience and improving clarity in winner management. The changes include tracking absent participants, marking winners as absent, redrawing replacements, and updating the UI to reflect these updates.

New Features for Absent Winner Handling:

• Added a new session state variable, absent_participants, to track emails of absent winners. This is integrated into the session reset logic. (app.py: [1] [2]
• Introduced a mark_winner_absent function to mark winners as absent, add them to the absent participants list, and redraw replacements if possible. Replacement winners are flagged and linked to the original absent winners. (app.py: app.pyR200-R249)

Enhancements to Winner Display and Statistics:

• Updated the winner display logic to differentiate between original winners and replacements. Added visual indicators for absent winners and replacement winners in the UI. (app.py: app.pyL321-R446)
• Enhanced statistics to show total winners, absent winners, and final prize recipients, providing clearer insights into the raffle outcome. (app.py: app.pyL217-R297)

Prize Assignment Improvements:

• Adjusted prize assignment logic to account for replacements, ensuring prizes are correctly matched with original winners or their replacements. (app.py: app.pyL351-R494)

Minor Changes:

• Updated the Makefile to ensure the run target stops any existing container before starting a new one, improving reliability during development. (Makefile: MakefileL9-R9)
