wpcomsh: Mirror POSTS_TO_PODCAST tier features from wpcom (#48776)

* wpcomsh: Mirror POSTS_TO_PODCAST tier features from wpcom

Mirrors the wpcom-side change (Automattic/wpcom#217049) that introduces
plan-tiered monthly quotas for the Posts to Podcast endpoint:

  POSTS_TO_PODCAST_TIER_1 → Personal+   (5 generations / month)
  POSTS_TO_PODCAST_TIER_2 → Premium+    (10)
  POSTS_TO_PODCAST_TIER_3 → Business+   (20)

Sites accumulate tiers through the existing _AND_HIGHER plan cascades;
the lib's quota helper on the wpcom side reads from the highest tier
down and returns on the first hit.

* wpcomsh: Drop comment that broke phpcs alignment cascade

The three-line comment above POSTS_TO_PODCAST_TIER_1 split the
existing const-declarations alignment block in two, which made phpcs
demand re-padding for the 60+ unmodified constants that follow. The
constant names are self-documenting and the tier→quota mapping is
documented at the FEATURES_MAP entries below; drop the constants-block
comment to restore the prior alignment.
