This pull request adds a new feature to log ticket closures in a dedicated logs channel, with contextual information and a link to the ticket panel, across both manual and scheduled closure flows. The change is implemented for close and force-close commands (both slash and text), as well as scheduled closure operations. It also introduces localized log messages in English and French.

Logging and Notification Enhancements

• Added logic to send a log message to a configured logs channel whenever a ticket is closed (manual, force, or scheduled), including the user's name, user ID, and a direct link to the ticket panel. This is conditional on the enable_logs config setting and presence of a logs channel ID. (rustmail/src/commands/close/slash_command/close.rs, rustmail/src/commands/close/text_command/close.rs, rustmail/src/commands/force_close/slash_command/force_close.rs, rustmail/src/commands/force_close/text_command/force_close.rs, rustmail/src/modules/scheduled_closures.rs)

• Ensured that log messages are sent in both English and French, with appropriate translations for the ticket closure log entry. (rustmail/src/i18n/language/en.rs, rustmail/src/i18n/language/fr.rs)

Codebase Maintenance

• Added necessary imports for utility functions used in the new logging logic. (rustmail/src/commands/force_close/slash_command/force_close.rs, rustmail/src/commands/force_close/text_command/force_close.rs)
