Standardize naming for files + urls

[wes-otf]

A kinda simple one but it might make sense to "standardize" how we name things a bit. A few examples:

Partial names between projects & applications are snake vs kebab case, and applications specify partial in the name:

hypha/hypha/apply/projects/urls.py

Lines 85 to 86 in 9185a07

	path("partial/lead/", partial_project_lead, name="project_lead"),
	path("partial/title/", partial_project_title, name="project_title"),

hypha/hypha/apply/funds/urls.py

Line 173 in 9185a07

name="partial-get-lead",

the same applies to filenames, there's a mix of snake & kebab in templates

Is there a difference between naming folders include or includes?:
ie. /apply/activity/templates/activity/include/ vs /apply/templates/forms/includes/

definitely not a priority, just was noticing it a bit as I was poking around today and wanted to document

I find it a lot easier to find and remember things that are named consistently so +1.

I'll try clean this up.
