feat: always offer the 30-day trial (#3798)

The 7/14/30 trial-length split has been called — 30 won on signups.

pickCmemProTrialDays() returns 30 instead of drawing an arm; the signup
URL, offer copy, and trial-start call already took the length as a
parameter. 7 and 14 stay valid on cmem.ai and in parseCmemProTrialDays,
we just stop selecting them.

The session-start banner, context banner, welcome hint, viewer header,
and cursor-hooks docs said "7-day trial" and linked to /pro with no
trial param — cmem.ai buckets a paramless visitor into 7/14/30 itself,
so those clicks could still land on a 7-day trial. They now read a
single PRO_TRIAL_DAYS constant and pass trial=30 explicitly, with a test
keeping the viewer's mirrored copy in step.
