chore(deps): refresh app/full composer.lock

Updates all in-constraint dependencies of the full image:

- guzzlehttp/guzzle  7.12.0 -> 7.12.1
- guzzlehttp/psr7    2.12.0 -> 2.12.1
- aws/aws-sdk-php    3.385.0 -> 3.385.3
- brick/math         0.14.8 -> 0.18.0
- google/cloud-core  v1.72.2 -> v1.72.3
- google/common-protos 4.14.0 -> 4.14.1
- ramsey/uuid        4.9.2 -> 4.9.3

Trigger was the scheduled Security Scan failing on trivy (full) after
three Guzzle advisories were published 2026-06-19 (CVE-2026-55766 in
psr7, CVE-2026-55767 and CVE-2026-55568 in guzzle); the Guzzle bumps
resolve those. The remaining bumps are incidental, picked up by the
same composer update.

Root app/ composer.lock is unchanged: every package there is already at
the highest version phpbu/phpbu ^6.0 allows (newer symfony/process 8.x
and sebastian/environment 9.x lines are gated by that constraint).
