Improve SKU catalog hygiene and BOM accuracy

- refresh_sku_catalog.py: add --discover to report API SKUs missing from
  catalog, filtered to already-curated serviceCategory values. Auto-runs
  at end of --validate and --refresh so gaps surface on every maintenance
  pass. First run found 162 missing SKUs (Blackwell GPUs, X12 Ax compute,
  VMware reserved tiers, WebLogic-on-OKE, Analytics/OIC BYOL).
- oci_bom_gen.py: fix Cost % column being blank. Back-fill was gated on
  formula detection but data rows write raw numbers, so the predicate
  never matched. Now tracks data_item_rows explicitly.
- .gitea/workflows/sku-catalog-refresh.yaml: monthly automation (1st at
  09:00 UTC). Auto-refresh prices → push branch + open PR; detect new
  SKUs → open issue with labels. Gated on secrets.GITEA_TOKEN.
- kb/pricing/oci-sku-catalog.yaml: add B95714 / B95715 (Autonomous ATP
  Dedicated ECPU, LI + BYOL) — canonical SKUs for ADB-D pricing.
- kb/services/compute.yaml: add X12 family (VM.Standard4.Ax.Flex,
  BM.Standard4.Ax.120), E6.Ax and A4.Ax variants. Verified against
  docs.oracle.com computeshapes.htm. Bump last_verified + changelog.
- templates/bom-spec.yaml: document 730 hrs/month convention as default
  (= real annual billing / 12; 744 overstates by 1.92% on 12-month TCO).
- Makefile: new 'make sku-discover' target.

+# Monthly SKU catalog refresh.
+#
+# Runs on the 1st of each month at 09:00 UTC and on manual dispatch.
+#
+# Does two things:
+#   1. `--refresh`: pulls latest PAYG prices from Oracle's public API,
+#      updates kb/pricing/oci-sku-catalog.yaml, and opens a PR if anything
+#      changed.
+#   2. `--discover`: reports SKUs present in the API but absent from the
+#      catalog (filtered to serviceCategory values already curated).
+#      If new SKUs are found, opens a Gitea issue listing them by category
+#      for manual review.
+#
+# Tokens:
+#   secrets.GITEA_TOKEN — must have repo:write + issues:write.
+#   If not set, the run logs the diff/discover output as an artifact and
+#   leaves the rest (branch push, PR, issue) as a no-op.
