fix(emcn): Calendar icon collision + prism side-effect registration

[waleedlatif1]

Summary

Two regressions surfaced after the @sim/emcn extraction (#5257):

• Calendar icon rendered a date picker (e.g. the Scheduled Tasks header). The barrel resolves the Calendar name-collision to the date-picker component (symmetric with Table). Scheduled-tasks imported Calendar from the barrel but used it as an icon, so it rendered the picker. Routed the icon consumers (scheduled-tasks.tsx, loading.tsx) to @sim/emcn/icons, matching the "icons come from the /icons subpath" convention. Added a barrel note so the component re-export isn't re-introduced.
• Prism is not defined on page load. The package's new sideEffects: ["**/*.css"] marked code/prism.ts as side-effect-free, but it registers prismjs languages on the global Prism (a real JS side effect). The bundler could drop/reorder its core init. Added code/prism.ts to sideEffects.

Type of Change

• Bug fix

Testing

• Calendar fix: apps/sim typecheck clean (0 errors); a comprehensive sweep confirms no remaining collision-named icon (Calendar/Table) is imported from the barrel as an icon. High confidence.
• sideEffects fix: config-correct (prism.ts genuinely has JS side effects), but it's a bundler-level change that typecheck/static analysis cannot confirm — needs a runtime check on a real build to verify Prism is not defined is gone.

Not in scope (verified NOT emcn-caused)

• Malformed <path> d SVG warnings live in apps/sim/components/icons.tsx (block icons), which the emcn move never touched — pre-existing on main.
• React chore(deps): bump the workspace-dependencies group with 22 updates #418 is a hydration mismatch, not something a mechanical component move introduces.

PR Summary

Low Risk
Targeted import-path and bundler metadata fixes with no auth, data, or API behavior changes.

Overview
Fixes two regressions from the @sim/emcn package split.

Scheduled Tasks header imported Calendar from the main @sim/emcn barrel, which resolves Calendar to the date-picker component (same name collision as Table). The header and loading fallback now import Calendar and Plus from @sim/emcn/icons so the chrome shows the icon, not the picker.

@sim/emcn package.json now lists **/components/code/prism.ts in sideEffects alongside CSS. With only **/*.css marked, the bundler could treat prism language registration as dead code and drop or reorder it, causing Prism is not defined at runtime.

Greptile Summary

This PR fixes two regressions from the EMCN extraction. The main changes are:

• Scheduled-tasks icon consumers now import from @sim/emcn/icons.
• The Calendar name collision stays resolved to the date-picker component in the main barrel.
• The Prism registration module is listed as a JavaScript side effect in packages/emcn.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The icon subpath exports the changed symbols.
• The Prism side-effect entry matches the source package layout used by consumers.

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/scheduled-tasks/loading.tsx	The fallback header icons now come from the EMCN icons subpath.
apps/sim/app/workspace/[workspaceId]/scheduled-tasks/scheduled-tasks.tsx	The scheduled-tasks header action icons now use the icon export path.
packages/emcn/package.json	The Prism registration file is now marked as side-effectful for bundlers.
