Fix review findings from adversarial review of L5-L8 slides

1. L6 recap: add missing m_u in scale height formula H = kT/(μ m_u g)
   (was dimensionally wrong without it)

2. L8: fix Mars crust thickness from "25-45 km" to "24-72 km" to match
   InSight results cited in the lecture notes and the earlier L8 slide

3. L5: fix "Next lecture" subtitle from "Climate, Habitability, & the
   Runaway Greenhouse" to correct "Clouds, Weather, & Climate"

4. L7: fix recap that incorrectly attributed L5 topics (greenhouse,
   escape) to L6; now covers both L5 and L6 correctly

5. L6: fix GRS observation claim from "continuously for >350 years" to
   "first recorded 1664; continuous observations since ~1830" (matching
   the more precise statement in the lecture notes)
