Issue:
Support localized Modified date time in Open Project project listing
Currently the "Last Modified" column in the project listing on the Open Project page has the date and time hard coded in pseudo ISO 8601 format. It would be desirable to have the date times formatted using the localized format for the user, while also retaining the ability to sort the column in descending (default) or ascending order

### Proposed solution
There are probably several possible solutions, but here are two:
- Prepend a hidden span to the formatted date - https://stackoverflow.com/a/15114891/167425
- Use a custom parser - https://mottie.github.io/tablesorter/docs/example-parsers-advanced.html

### Alternatives considered
Switch to a different sortable table package that supports Dates natively

### Additional context
<!-- Add any other context or screenshots about the feature request here. -->


Pull request description:
Localize date on Open Project page. Fixes #6172
Fixes #6172. Built on #6169.

Changes proposed in this pull request:
- format dates according the the language the user set in
  OpenRefine preferences with browser language as fallback
- right justify numbers in Row Count column
- consolidate CSS for project name
- fix pre-existing CSS off-by-one errors
- fix unrelated typo with user metadata
