Watchfolio v3.0, upgrade 3

Creation of version 3.0.3/2023 and completion of Playlist 03 (Legal Concerns).

In progress: indexation of existing and added content (added a "Status: Uncategorized" tag to locate the items left to be indexed).

Please note that the indexation (or categorization) process is a time consuming task which requires a lot of hard drive-based (internal) cross-referencing prep work meant to keep the original release timeline consistent with my own operations research-focused rationale.

Update completed on 2023-07-21.
