fix(sessions): clarify "PostHog products used" bar and drop misleading Code link

[k11kirky]

Problem

Users hit the bar above the message composer and didn't understand it (per a Slack thread). Two specific issues:

• The header "PostHog resources used" doesn't explain what it's telling you.
• The "Code" chip linked to the posthog.com/code marketing landing page — a dead-end destination. It only means "the agent read files from your repository", not a PostHog data product.

Changes

• Renamed the header to "PostHog products used" with a tooltip explaining it lists the PostHog products the agent drew on this session.
• The "Code" chip no longer links to the /code landing page; it now shows an explanatory tooltip instead.
• Every chip now has a hover tooltip (docs link for product chips, a short explanation for informational ones).

No behavioural change to what gets tracked — only how the bar is labelled and what the chips do on click/hover.

How did you test this?

• tsc -p tsconfig.web.json --noEmit (renderer typecheck) — passes.
• vitest run accumulateSessionResources — 3 tests pass (accumulation logic unchanged).
• biome check on the changed file — clean.

### Issue 1 of 1
apps/code/src/renderer/features/sessions/components/SessionResourcesBar.tsx:118-120
The tooltip fallback for products with no `docUrl` and no `PRODUCT_TOOLTIP` entry is `product.label`, which is the same text already visible in the badge. For `apm` this means hovering the chip shows a tooltip that adds no information. Either add an `apm` entry to `PRODUCT_TOOLTIP` (mirroring the `code` treatment) or omit the tooltip when there's nothing extra to say, to avoid a superfluous interaction.

```suggestion
            const tooltip =
              PRODUCT_TOOLTIP[product.id] ??
              (docUrl ? `Open ${product.label} docs` : undefined);
```
