Include current version in profile/settings backup file name

[Copilot]

Backup filenames for settings and profiles now include the application version between the timestamp and original filename: <timestamp>_<version>_<original_filename>.

Changes

• TimestampHelper.GetTimestampFilename — Added optional version parameter. When provided, dots are replaced with dashes and the segment is inserted between the timestamp and filename. Backward-compatible (omitting version preserves existing behavior).
• SettingsManager.CreateDailyBackupIfNeeded — Passes AssemblyManager.Current.Version.ToString() to GetTimestampFilename.
• ProfileManager.CreateDailyBackupIfNeeded — Same.

Example output

# Settings
20260201010630_2026-3-4-0_Settings.json

# Profiles
20260201010738_2026-3-4-0_test.encrypted
20260201010746_2026-3-4-0_Default.xml

Existing CleanupBackups logic (IsTimestampedFilename + Contains($"_{name}.")) continues to work correctly with the new format.

Copilot summary

TimestampHelper.GetTimestampFilename gains an optional version string parameter. When supplied, the method replaces dots with dashes and inserts the version between the timestamp and the original filename (e.g., 20260201010630_2026-3-4-0_Settings.json). Both SettingsManager and ProfileManager are updated to pass AssemblyManager.Current.Version.ToString(), so all daily backups now embed the running application version. The IsNullOrWhiteSpace guard ensures no stray underscores appear if a blank version is ever passed.
