Closes #15618: Always use ISO 8601 date & time formatting (#15737)

* Introduce the isodate(), isotime(), and isodatetime() template filters

* Display the relative time on mouse hover

* Render journal entry times in ISO 8601 format

* Use ISO 8601 format when displaying dates & times in a table

* Standardize the use of DateTimeColumn across all tables
