Explaining historical mail log analysis

- Added a dedicated section about analyzing saved historical mail logs.

- Described timeline replay with pause, fast-forward and seek controls.
Q&A, translations and search metadata
- Added the question: Can I visualize historical log files?
- Clarified that file analysis runs in the desktop application and does not require an SSH connection to the server.
- Added equivalent content to the Japanese and English pages.
- Updated page descriptions, feature-list structured data and FAQ structured data to match the visible content.
Using the feature
Open a saved Postfix plain-text log in the LogGraphic desktop app, or drag and drop the file. Set the log start date and time to display and aggregate events from that point onward.
