Earmark conjunctive combinators from the funding page

[AdamSpitz]

Summary

CauseStarter now mints a conjunctive (all) combinator as part of earmarking funds for a selected bundle of statements, then opens the existing pledge form against that CID.

• Funding page: select ≥2 published statements → Earmark for all N selected.
• ensureCombinatorPublished reuses the shared combinator CID when it already exists.
• Implication-attester payment is skipped on this path so a NoteIntent is not blocked on pairwise arrows.
• Removed the generic cause-page Promote as any / all buttons. Combinators are created from the action that needs them.
• Founder notes record which operator belongs to which job (any is still Ask — do not auto-mint from bridges).

Test plan

• Open a cause with ≥2 published planks → funding page.
• Single-plank Make a pledge still goes to /delegation/notes/new?statement=<plank>.
• Check two planks, earmark: first time publishes the combinator (wallet txs), then lands on the pledge form with the combinator CID.
• Repeat the same pair: no republish, same CID.
• Cause page view strip no longer shows Promote buttons.
• Disconnected wallet: earmark asks to connect instead of starting a publish.

Review gate: run /code-review --comment and scripts/post-review.sh before merge (project workflow).

Review receipt.

Conjunction earmark from funding page is the right operator/job split. Reuse via ensureCombinatorPublished + sorted CIDs is correct; skipping attester payment on this path is documented and matches NoteIntent needs. Fixed stale founder 'what exists' blurb that still described generic cause-page promote. Remaining any-mint path is already Ask on causestarter/TODO.md.
