Finish the 6.1.4 stone compatibility fixes for Forge 26.3

[SkyBlade1978]

This finishes the stone compatibility fixes for Mineralogy 6.1.4 on Forge 26.3.

• Sculk catalysts, moss, dripstone and azalea roots recognise natural Mineralogy terrain. The direct dripstone checks are fixed too, without making every Mineralogy block a vanilla ore host.
• Bats and goats can use the appropriate natural rocks, and goats can lose horns against the harder raw rocks. Crafted and soft rocks stay out of the horn list.
• Sulfur cubes can absorb the 31 raw Mineralogy rocks as Slow Bouncy stones. Polished blocks, bricks and every other crafted Mineralogy item are excluded. Minecraft's own consumption rules are left alone.
• Slabs, stairs, walls, furnaces, ores, storage blocks and coloured drywall have their missing classifications. Separate double slabs remain full blocks.
• Rock-salt lamps keep the centre post on straight walls, and cats can sit on lit rock furnaces, but not unlit ones.
• Turning construction blocks off no longer breaks their tags or loot tables. Enabled drops are unchanged, and normal cobblestone follows the existing equivalence setting.

Existing worlds get the behaviour fixes after updating. Cave decoration changes apply to new chunks; this won't redecorate explored caves. Vanilla and other mods' tag entries are preserved, with cobblestone equivalence both on and off.

This is 6.1.4.2603001 for Minecraft 26.3, Forge 66.0.0 and Java 25, using released OreSpawn 4.0.16.2603001. Registry IDs, configs, migrations, textures, enabled recipes and OreSpawn's provider/settings are unchanged.

Local checks pass: 79 tests, release and Eclipse gates, two matching assemblies, both cobblestone modes and disabled construction, real behaviour tests, paired 81-chunk cave samples, and packaged client/server fresh starts and reloads. Complete logs were reviewed; platform and offline-account messages are accounted for, with no crashes or unexplained product failures. Agent notes and generated test output aren't committed, and probes don't ship.

The wider OreSpawn generation and legacy-world qualification is inherited from the unchanged port rather than rerun for these fixes. This replaces the earlier partial candidate and its broader sulfur-cube policy.
