Mark the RS lists with a debug-only "(RS)" title suffix

[nbradbury]

Description

Posts, Pages, and Comments each have two implementations: legacy FluxC and WordPress-RS. They look close enough that it's hard to tell which one is on screen, which is a problem for us when testing.

This PR resolves this by adding (RS) to the screen titles in debug builds only.

Testing instructions

RS screens show the suffix (debug build)

1. Install a debug build and sign in to a site that authenticates with an application password.
2. My Site → Posts.

• Title reads "Blog Posts (RS)"

3. Back, then My Site → Pages.

• Title reads "Site Pages (RS)"

4. Back, then My Site → Comments.

• Title reads "Comments (RS)"

FluxC screens have no suffix

1. On the same site, go to My Site and tap the drafts or scheduled posts card.

• The legacy list opens with title "Blog Posts" — no suffix

2. Sign in to a WordPress.com site that has no application password, then open Posts, Pages, and Comments.

• All three open the legacy screens with no suffix
