* feat: auto-detect and correct ZFS blocksize for TrueNAS SCALE/CORE (#241)
SCALE requires >= 16k volblocksize; CORE works with 8k. Without correction,
creating a disk on SCALE with blocksize=8k triggers a ZFS warning and wastes
space on SCALE's minimum-4k-block pool layout.
Three changes:
- freenas_get_recommended_blocksize: fixes freenas_api_connect → freenas_api_check
so product_name is actually populated before the SCALE check (was always returning
8192 before this fix)
- freenas_parse_blocksize: new helper to compare "8k"/"16k"/integer blocksize strings
- alloc_image (both 8.x and 8.4.x patches): always detect recommended blocksize for
freenas provider; if configured < recommended, override for this call AND persist
the correction back to storage.cfg via lock_storage_config
- on_add_hook (8.4.x patch only): detect at storage creation time and correct $scfg
before write_config saves it — no extra write needed
Tested on pve01-hq (PVE 8.4.19) against Tank02 (SCALE 24.10.2.1):
- Disk created with blocksize=8k → task log shows correction message, storage.cfg
updated to 16384, no volblocksize warning from TrueNAS
- Disk created with blocksize=16384 → no-op, clean TASK OK

* ci: add validate-patches step for ZFSPlugin PVE 8.4.x patch
ZFSPlugin-8.4.14_1.pm.patch has been in the build since v2.3.0 but was
never dry-run validated in CI. Now that we have the 8.4 orig committed
(ZFSPlugin-8.4.14_1.pm.orig from libpve-storage-perl 8.3.8), wire it up.

* fix: replace explicit return undef with bare return (perlcritic)
Subroutines::ProhibitExplicitReturnUndef violation in
freenas_get_recommended_blocksize. Bare return in list context returns
an empty list rather than a list containing undef, which is the
correct Perl idiom.
