fix(misc): skip missing ship templates in global build imports

[ggmolly]

Summary

• Prevent startup data updates from failing when global build metadata references ship templates absent in the selected region.
• Keep region-specific ship datasets authoritative by skipping unmapped pool/build-time rows instead of aborting the transaction.
• Add regression coverage for template 10400031 to ensure missing-template handling stays non-fatal.

Changes

• Updated importPoolsSQLC to warn and continue when SetShipPoolID affects zero rows.
• Refactored build-time application through applyBuildTimes(...) and made zero-row updates warn-and-skip.
• Added end-of-step warning summaries for skipped pool/build-time mappings.
• Added TestApplyBuildTimesSkipsMissingShipTemplate in internal/misc/update_data_sqlc_test.go.
