fix(blocks): render SubBlockConfig.tooltip in sub-block label

[sanidhyasin]

Summary

SubBlockConfig.tooltip is defined in apps/sim/blocks/types.ts (tooltip?: string // Tooltip text displayed via info icon next to the title) but was never rendered. renderLabel in sub-block.tsx reads config.title and config.required but ignored config.tooltip, so block configs that set it — e.g. pi.ts and textract.ts — showed no help text in the editor.

This wires up the field: when config.tooltip is set, an Info icon is rendered next to the field title, and hovering it shows the tooltip text. It reuses the Tooltip.Root/Trigger/Content pattern already used a few lines below in the same renderLabel for the invalid-JSON warning, and matches its icon styling (size-3, flex-shrink-0, text-muted-foreground).

Fixes #4071

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation
• Other: ___________

Testing

• bunx @biomejs/biome check on the changed file passes with no fixes/warnings.
• Verified the existing block configs that already set tooltip (pi.ts, textract.ts) now surface an info icon with their help text next to the corresponding field label; fields without a tooltip are unchanged.
• This is a small, presentational addition that mirrors an existing rendering branch in the same function; there is no existing unit-test harness around renderLabel, so no test was added.

Reviewers: the only behavioral change is the new conditional block inside renderLabel; everything else (required asterisk, label suffix, invalid-JSON warning, copy/wand/toggle controls) is untouched.

Screenshots/Videos

With a sub-block that sets tooltip (e.g. the PI block's "Personal access token" field), an info icon now appears immediately after the field title; hovering it shows the configured text. Fields with no tooltip render exactly as before.

PR Summary

Low Risk
Presentational UI-only change in the editor label row; no data, auth, or execution paths affected.

Overview
Fixes missing help text for workflow block fields that already define tooltip on SubBlockConfig (e.g. PI and Textract blocks).

When config.tooltip is set, renderLabel now shows a muted Info icon beside the field title; hover displays the configured string via the same Tooltip pattern used for the invalid-JSON warning. Fields without tooltip are unchanged.

Greptile Summary

This PR renders configured sub-block tooltips in the editor label area. The main changes are:

• Adds the Info icon to the existing lucide-react import.
• Shows an info icon when config.tooltip is present.
• Uses the existing Tooltip.Root, Tooltip.Trigger, and Tooltip.Content pattern near the sub-block label.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
