Andrey KolkovandClaude Opus 4.8 82aa967674 test(e2e): correct the round-trip budget and its stale comments
Second review pass on this branch.

1. The op timeout equalled the inner sum instead of exceeding it: the comment
   enumerated 3900s of inner waits and then set 65m, and 3900s IS 65m — so there
   was zero headroom for the applies and SQL calls between those waits, and the
   claim of "room" was false. Sized the inner budgets against what CI actually
   takes instead (the bucket suite completes in ~37s and a backup-enabled
   ClickHouse plus Keeper reaches Ready in ~98s, measured on run 30353894332):
   bucket claim/access 300->180 and the three job waits 600->480, summing to
   3300s, under a 60m op timeout. Shrinking the inner budgets rather than
   raising the ceiling also keeps this suite closer to its postgres and mariadb
   siblings on a 180-minute job cap.

2. The strategy Pod's securityContext comment still justified root with "Pod
   runs apk add at startup", which the previous commit made conditional — the
   default path now runs the platform's pre-baked image and installs nothing.
   Scoped the note to the alpine fallback and said explicitly that the field set
   matches cozy-default-altinity, runAsNonRoot deliberately unset in both.

3. clickhouse-backup.yaml still referenced clickhouse-backup-{1-contracts,
   2-roundtrip}: the file moved unchanged, so the Test rename never reached its
   own header and a reader following either name found nothing.

4. wait_sts_ready's timeout diagnostic could not print anything. It selected
   clickhouse.altinity.com/chi=${name#chi-}, which yields
   clickhouse-<app>-clickhouse-0-0 while the label carries the CHI name
   (clickhouse-<app>), and 2>/dev/null then swallowed kubectl's "No resources
   found". Ask for the StatefulSet's own first replica by name instead and let
   both streams through; verified it now surfaces the Pod events that explain
   why the replica never came up.

Also dropped the clickhouse bats case added in the previous commit: it asserted
what the generic examples/backups/<app> -> <app> mapping already guarantees, so
it did not lock the invariant its comment claimed. That invariant is now
recorded where it belongs — in the mapping's own comment in select-e2e.sh.

The dedicated ch-backup-client image this example now inherits is tracked in
#3420; noted there that the command: override is load-bearing in two files.

# cozytest.sh's awk parser recognizes only @test blocks and a bare `}` on its
# own line; there is no bats `run` or `$status`. Each test runs as a shell
# function under `set -eu -x`, so assertions are direct shell tests that exit
# non-zero on failure. setup()/teardown() are not honored — each test creates
# and cleans its own scratch dir.
