feat(ui): Add slack manifest generator

[TheodoreSpeaks]

Summary

Previous slack instructions had the user directly editing scopes. Slack's ui can be confusing, we should auto-generate a manifest that they can use.

Created a slack setup wizard to do this. Allows user to specify the scope and gives direct step by step instructions that auto paste into correct subblocks.

PR Summary

Medium Risk
Adds a new modal sub-block type and a Slack setup wizard that writes secrets/tokens into workflow state, so regressions could affect trigger configuration and credential handling in the editor UI.

Overview
Adds a new Slack app setup wizard UI that generates a Slack app manifest from selectable capabilities, provides step-by-step setup guidance, and writes botDisplayName, signingSecret, and botToken into the existing sub-block store for the Slack webhook trigger.

Introduces a new SubBlockConfig type modal resolved via a client-side MODAL_REGISTRY, updates the Slack webhook trigger to use this modal instead of the previous long HTML instruction text, and enhances checkbox-list options with defaultChecked + description (tooltip + default fallback behavior).

Also adds new emcn primitives Wizard and SecretInput (mask-on-blur), updates sub-block type validation to include modal, and includes a small UI class order tweak in the CSV import dialog plus a generated tool schema key formatting change.

Greptile Summary

This PR introduces a multi-step Slack App Setup Wizard that auto-generates a Slack manifest from user-selected capabilities, guiding users through app creation and credential entry. It adds a reusable Wizard EMCN component, a modal sub-block type dispatched via a new client-side MODAL_REGISTRY, and a buildSlackManifest utility in the trigger layer.

• navigator.clipboard.writeText in StepCreate.handleCopy is not awaited — any clipboard rejection silently fires the "Copied!" success state, misleading the user.
• SecretInput.onChange passes e.target.value unconditionally; when isFocused is false, displayValue is bullet characters, so a programmatic change event would overwrite the stored secret with •••....

Confidence Score: 4/5

Safe to merge after fixing the clipboard async/error handling and the SecretInput onChange guard.

Two P1 issues exist in the wizard UI: unhandled clipboard Promise gives false success feedback, and SecretInput onChange can write bullet characters to the store. Both are confined to the wizard and don't affect data in normal usage, but should be fixed before merge.

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/slack-setup-wizard/slack-setup-wizard.tsx	Main wizard UI component — two P1 issues: clipboard write not awaited (false success feedback) and onChange called with bullet chars when blurred.
apps/sim/triggers/slack/capabilities.ts	Defines SLACK_CAPABILITIES and buildSlackManifest; well-structured with correct deduplication, placeholder when webhook URL is absent, and no event_subscriptions block when empty.
apps/sim/components/emcn/components/wizard/wizard.tsx	New reusable Wizard EMCN component — clean design, but progress bar uses step title as React key which could break for duplicate-titled steps.
apps/sim/triggers/slack/webhook.ts	Adds the modal-type setupWizard sub-block to the Slack webhook trigger config, wiring it to the new registry entry.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/modal-registry.ts	New client-side modal registry pattern; clean and extensible, correctly keeps config decoupled from component imports.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/sub-block.tsx	Adds modal case to the sub-block renderer switch; lookup falls through the registry cleanly with a graceful error state for unknown IDs.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/checkbox-list/checkbox-list.tsx	Adds tooltip support for checkbox options; minimal change, correctly follows existing patterns.
