BambyTrace

- Improved the options layout so help text no longer overlaps the history filter or clips against the bottom edge.
- Made the centered `0 / 0` counter visible when the current session has no readable entries and the native count is zero.
- Balanced saved-history arrows evenly around the page counter, including when the current session is empty.
- Added history filters for errors and warnings, with text selection for manual copying using Ctrl+C. BambyTrace does not access the system clipboard.
- Added an option to turn off persistent error-history storage. Turning it off asks for confirmation and clears saved details; new readable entries remain in memory only until reload.
- Added English and German text for the history and options labels
- Restored the original error window size of 560 × 250 UI units.
- Made all three session tabs the same width and centered their complete row in the window for balanced spacing.
- Kept the saved-history arrows and page counter centered as a separate group, with matching left and right arrow spacing.
- Left Blizzard's native error-window arrows unchanged.
