feat: Add recipe count to header of recipe card section

[jannon]

What this PR does / why we need it:

This just adds the recipe count to the header of the recipe card section. It provides a useful piece of information right at the top of the section so users can see how many total recipes or how many match the filters/search.

So it goes from 'Recipes' to 'Recipes (n)' where n is the number of recipes in the result.

Which issue(s) this PR fixes:

This is a small change looking to enhance the usability/convenience of the UI. It's a common UI paradigm to display the number of items in a collection somewhere near the top.

Special notes for your reviewer:

I just starting using mealie and found myself wanting this. I thought this was a nice simple change to start to familiarize myself with the project. I don't think it warranted any test or doc changes, but let me know if there's anything else I should do.

Testing

Visual testing with the development UI:

• Upon start, displays 'Recipes (0)'
• After adding a recipe, displays 'Recipes (1)'
• After adding another, displays 'Recipes (2)'
• After searching for something specific to one of the recipes, displays 'Recipes (1)'

Won't this only show the currently fetched recipes (i.e. after pagination)? We return the true "total" with the pagination API, should we use that value instead?

[michael-genson]

This is what the API returns:

mealie/mealie/schema/response/pagination.py

Lines 53 to 60 in 93c2df4

	class PaginationBase(BaseModel, Generic[DataT]):
	page: int = 1
	per_page: int = 10
	total: int = 0
	total_pages: int = 0
	items: list[DataT]
	next: str | None = None
	previous: str | None = None

[jannon]

Ah, I see. I hadn't encountered any pagination yet in my usage. I'll have a look and take another pass

[michael-genson]

IIRC the frontend pulls two pages at once (with a page size of 32 that's 64 recipes) so you might want to add 100 recipes or so to your dev instance

I like the idea, see my comment though, I'm not sure this will work as-is. Also, would you be able to include a screenshot of what it looks like?
