Improvements for working with large text fields

[seancolsen]

Overall problem

Working with large text fields in Mathesar is cumbersome.

A "large text field" is defined as any cell which contains a long string. Strings containing a few words are relatively easy to work with. Strings containing multiple sentences, multiple lines, and/or multiple paragraphs are problematic.

Specific problems and ideas

• In a "sheet view", it's hard to view and edit large text fields. Show cell content in table inspector Cell tab #2342 Will help with this, but we might need more help. It might be nice to view/edit a single cell within a modal or potentially a dedicated page (which could be opened in a new tab). This "sheet view" is used on the table page, the various exploration pages, and the table widget within the record page.

• The record view at the top of the record page, you can view/edit text fields within a textarea input, which is nice. However, it would be nice if we could configure the height of that textarea so that certain fields always use tall inputs for convenience.
