ci: add count-floor guard to migration-critical test gate (#4673)

The migration-proof step in ci.yml selects tests by name substring
(data_movement / rebalance / decommission / source_cleanup /
delete_marker), so a rename can silently thin the gate to zero with no
CI signal. Move the filter expression into
scripts/check_migration_gate_count.sh as its single source of truth:
the script counts the selected tests with cargo nextest list, fails if
the count drops below the committed floor in
.config/migration-gate-floor.txt, and then runs the gate with the same
filter so the check and the run cannot drift.

The floor equals the exact selected-test count at landing (571), so any
reduction fails CI and intentional shrinks must edit the floor file in
the same PR, keeping gate changes visible in diffs.

Refs rustfs/backlog#1153 (infra-12), rustfs/backlog#1155.

# Committed floor for the number of tests selected by the migration-critical
# CI gate (see scripts/check_migration_gate_count.sh, backlog#1153 infra-12).
#
# The floor equals the exact count of rustfs-ecstore --lib tests matching the
# gate filter (name substrings: data_movement, rebalance, decommission,
# source_cleanup, delete_marker) at the time this file was last updated.
# CI fails if the selected count drops below this number, so renames or
# removals that thin the gate must update this file in the same PR.
# Adding tests does not require a bump, but bumping keeps the guard tight.
