v1.13.0.62

• Channels counter clarity (messages vs lines) - Channel header counter now shows message position within the currently renderable message window (1/N), not wrapped-line position. This makes counter behavior easier to understand when long messages consume many screen lines.
• Counter behavior explained - Message buffers are still DM=20 and Channels=100, but visible navigation depends on render cache (160 wrapped lines). With long texts, oldest buffered messages may be outside the current renderable window.
• Sound popup readability - Sound level popup shown on quick level cycling now stays longer on screen, so OFF/ON/LOW/MEDIUM/HIGH is easier to read.
• Sound cycle consistency - Added guard against accidental ultra-fast repeated toggles during triple-click bursts, making sound-level stepping more stable.
• Cyrillic read fallback - Incoming RU/UA/BY plus selected SR/MK Cyrillic text now has readable Latin fallback in UI (instead of disappearing characters), improving message readability on current fonts.
