upgrade-to-tls.md and upgrade-to-v2-jwt-removal.md are version-specific
runbooks for past releases. Late upgraders still need them; current
operators don't. Move both to docs/archive/upgrades/ with one-line
archive headers pointing readers at the current canonical docs.
Renames:
docs/upgrade-to-tls.md → docs/archive/upgrades/to-tls-v2.2.md
docs/upgrade-to-v2-jwt-removal.md → docs/archive/upgrades/to-v2-jwt-removal.md
Each gets a top-of-doc archive notice with the date and a forward
pointer to the relevant steady-state doc:
to-tls-v2.2.md → docs/operator/tls.md
to-v2-jwt-removal.md → docs/operator/security.md
The relative link inside to-v2-jwt-removal.md (was "upgrade-to-tls.md",
now "to-tls-v2.2.md") updated to point at its archived sibling.
Cross-reference updates from other docs and README still pending in
Phase 11.
