chore(info.xml): canonicalize PHP min, NC version range, licence spelling

Aligns appinfo/info.xml with the fleet canonical:

- <php min-version="8.3"> — matches the
  composer require.php constraint (^8.3 fleet-wide)
- <nextcloud min-version="28" max-version="34">
  — converge the fleet on one NC support range
- <licence>agpl</licence> — fix the casing/value drift
  (fleet had agpl / eupl / EUPL-1.2 / AGPL-3.0-or-later — 4 spellings).
  Stays on "agpl" workaround per the EUPL store-listing pattern;
  switch to "EUPL-1.2" once NC 34 is the fleet floor
  (ConductionNL/.github#98).

Per-app fields (<id>, <name>, <description>, <version>, etc.) are
preserved.

Drift surfaced in
