feat:chime: Enhance timestamp extraction in `chime--extract-time`

Expand `chime--extract-time` to handle plain timestamps alongside
scheduled and deadline timestamps. This enhancement includes parsing
timestamps from entry bodies, while avoiding duplicates from
planning lines. Updated and expanded unit tests to cover new
behaviors, including repeating timestamps and org-gcal integration,
ensuring robustness across different timestamp scenarios.
