Show and edit logic rules where they act

[PhilReinking]

Each rule now reads as a sentence under its question ("If “No”, go to 31 · Thank you! See you there."). Edit turns it into pickers in place. The open question gets a line and a blue number on where it jumps. The old logic panel is gone.

Fixes BITS-284

• Answers come from the source question: choices, rating range, date, number; text gets a case hint.
• Operators by type, as in the ticket; stored keys don't change.
• A rule using a deleted question shows red and can't be saved until fixed.
• Remove rule asks first, like the deletes from Ask before deleting a question, naming its answers and the rules that use it #269.
• Every rule control is 44 px below 1024 px.
• logic.showLogicEditor is gone: use addRule(block) from Document/Rules/ruleEditing.ts.

Heads-up: the card's "Rules (2)" is now "Add rule". A closed question's meta drops its rule count and says "Always hidden".

Tested: new Vitest tests, lint, vue-tsc, build. By hand at 1440, 768 and 390: edit, save, leave and return, add, remove, move; the public form follows an edited jump.

Not tested: a screen reader. Stacked PR, so no CI.

Known gap: removing a question's only rule leaves the cursor on the page.

Screenshots (1440, 390) are on BITS-284.

OK at 8bef14d. No CI (stacked), local runs: Vitest 323, lint, vue-tsc, build. No PHP change.

One should inline. Held: the new tests fail on the base, rules go out with the same fields as before (value always text, hide and show without a target), operators match the ticket, an old target on a hide rule draws no line, nothing else used the removed store parts, and answer labels show as text, never HTML.

The rule being edited is kept outside the page, so it stays open after you leave the editor. Back in the editor, that rule shows its pickers again and the cursor jumps into them. Ending the edit when its block's rules unmount fixes it, and a new rule that was never saved goes too:

OK at 5a39ee9 (re-check of 8bef14d..5a39ee9, now on part c). No CI (stacked), local runs: Vitest 387, lint, vue-tsc, build.

The should is fixed: leaving the editor ends the edit and drops an unsaved rule. Held: both merges keep parts a, b and c (only this PR's own lines change in the shared files), Remove rule asks first, Escape closes only that dialog, a failed remove keeps the rule, and the pill and the line mark the same jumps.

Landed in main with #282 (the editor rebuild as one PR); this PR's commits are part of it.
