remove reply keyboard; keep Clock In/Out as inline buttons only

- Removed smartKeyboard, defaultKeyboard, updateReplyKeyboard
- Removed statusMsg/keyboardMsg tracking from Handler
- sendText now sends plain messages (no reply keyboard)
- handleActionMsg sends result with mainKeyboard() inline keyboard
- handleActionCallback edits message with backKeyboard (unchanged)
- handleStart sends welcome + menu with mainKeyboard
- SendDailyReport sends plain text report
- Removed text-trigger 'Clock In'/'Clock Out' message handlers
  (only /clockin and /clockout commands remain)
