Dynamic Type should be supported throughout the app

Description

When changing the preferred text size in iOS, Pocket Casts should resize text appropriately.

Step-by-step reproduction instructions

1. Go to Settings > Accessibility > Display & Text Size > Larger Text
2. Change the slider at the bottom
3. Go to Pocket Casts
4. Check that text size has changed

Did you search for existing bug reports?

#30 has a task related to this, but it is not strictly about text sizing.

A few notes before I leave for AFK tomorrow.

I began working on this for several screens and most of this can be done by enabling adjustsFontForContentSizeCategory and using UIFont.TextStyles which are similar to our own. However, this will require going through every view and auditing every label, text view, and button so will take some time.

I think we have a choice here as to whether we want to reproduce our current font selection perfectly or whether we can vary some font sizes by a few points or change a few weights (as I did in my initial branch). UIFont+FontStyle does have methods to make it a bit easier to tweak font weights with existing styles, but we will need to do that in code. Should be fine in most cases as most of these are already hooked up to IBOutlets. If we want to verify pixel perfect accuracy, we could add some kind of view snapshotting to ensure we aren't inadvertently changing things.

I would love to have support for this.

However, this will require going through every view and auditing every label, text view, and button so will take some time.

This is the main concern I have, along with worrying about introducing new issues when making these changes.

My thinking has been to add support where we can which has been on new views (written in SwiftUI) and views that we are updating.

The benefit of using UIFont+FontStyle is that we are able to specify the maximum font size that we want to support which gives us the trade off of being able to support larger font sizes, and allowing them to still look good within our designs.

+1 in #7936880-zen:

iOS has a feature to define app specific font sizes. Unfortunately it doesn‘t work in the list views of the app (newest episodes for example). Does it make something wrong or is it not implemented?

Trying out Pocket Casts and liking what I’m seeing, however, there really needs to be a feature that allows for larger font/text size. Any chance of this feature coming to fruition? Or, am I overlooking the ability to do so? Thanks for the consideration!
