Support advanced Front Matter Title features

[WovenTales]

Now that I'm actually getting around to writing this, I suspect I was thrown off by the wording of the "Enable front matter title plugin integration" setting and that this doesn't actually integrate with the Front Matter Title plugin but instead merely emulates its main feature for consistency. If that's the case, then read this as "could this plugin go through that one for determining titles" -- what I'm asking is definitely complex enough that I wouldn't want it to be implemented separately.

Specifically, I have a custom template set up in Front Matter Title which adds the chapter number from a separate frontmatter field into the explorer (and only the explorer) and have taken heavy advantage of its ability to toggle replacement in some places but not others. However, those customizations aren't carried over to folder titles pulled from Folder Notes:

(There's a chapter: "2" defined for the "Database guide" folder note just like there is a chapter: "2.1" for the "Entry types" standalone, feeding into a template of {{chapter }}{{title}}.)

(I have tab title replacement set but not breadcrumbs (i.e. "Header") for files -- note how 1-types is just barely visible in the fade -- and without the supplemental chapter numbers, but Folder Notes has those two contexts coincidentally reversed.)
