Add closed-loop testing guidance and missing glossary terms

Adds 'Important Info For Testing Settings in Trio' callouts to the
three Core Concepts testing sections (Basal Rates, ISF, Carb Ratios),
recommending Max IOB = 0 and Autosens Min/Max = 100% while testing in
closed loop, plus a reminder to test basal rates before ISF/CR.

Adds 4 missing glossary terms: IAGE, OS-AID, SAGE, TDD.

Deliberately surgical, not a wholesale file replacement: dev has
independently evolved basal-rates.md and isf.md since #207 branched
(different 'Fasting is Essential' callout text, an updated pump
compatibility table including Medtrum Nano). Only the clearly new,
non-conflicting testing-guidance paragraphs were ported over; the
parts where dev's content differs from the PR were left untouched
rather than guessed at.

Not included from the original cleanup commits (a40de8f, db14841,
62bc3f0, 662df68, 00d14f1, e2569ba, 97bc3fa, 3b2a3f3, dec2361):
- Fixes to usage/ecosystem/*.md content are already baked into PR1
  (that PR took the final state of those files directly)
- 'Return App Diagnostics to index and mkdocs.yml' (a52784d): already
  present independently in current dev, nothing to port
- README.md revert: only a trailing-whitespace difference in current
  dev, not worth a change
- help/index.md changes (Discord/Facebook links, FAQ 'under
  construction' marker): unrelated to this commit's stated purpose
  and dev has diverged here too -- left alone rather than guessed at

Extracted from #207 (tmhastings), commit 7890536.
