Fix typography CSS: wrong selector + overly restrictive meta gate

CSS targeted .post-content but the theme template uses .entry-content.
Also removed the _prautoblogger_generated meta check — display settings
should apply site-wide to all posts, not just PRAutoBlogger-generated
ones.

Bump 0.7.0 → 0.7.1.

+### Fixed
+- **Typography CSS not applying.** Two bugs: CSS targeted `.post-content`
+  but the theme template uses `.entry-content`, and the
+  `_prautoblogger_generated` meta gate excluded posts that predate the
+  meta flag. Display settings now apply to all single post pages and
+  target the correct `.entry-content` selector.
