Add topic Bubble Up operations

[code-monger-givenall]

HEY has topic-level Bubble Up routes, but the SDK only covered the bulk posting versions. This adds the missing topic operations for scheduling a custom date, canceling a scheduled Bubble Up, and bubbling a topic up now.

The schedule request matches the form HEY expects:

• slot=custom in the query
• date=YYYY-MM-DD in the form body
• waiting_on=true only when requested

The service wrapper rejects invalid topic IDs and dates before making a request. The Smithy model, generated client, route coverage, behavior model, service tests, and conformance suite are updated together.

Tested against live HEY behavior for schedule, cancel, and Bubble Up now. make check passes with 130 conformance cases.

Summary by cubic

Adds topic-level Bubble Up operations to TopicsService so callers can schedule, cancel, or run Bubble Up immediately. Previously only bulk routes were supported; this adds topic routes with validation and correct form wire format.

• Adds ScheduleBubbleUp(ctx, topicID, date, waitingOn), CancelBubbleUp(ctx, topicID), and BubbleUpNow(ctx, topicID). Schedule uses slot=custom, optional waiting_on, and an application/x-www-form-urlencoded body date=YYYY-MM-DD.
• Validates topicID > 0 and date format; returns a usage error without sending a request on invalid input.
• Adjusts client header/path behavior: only append .json and set JSON headers when Accept is application/json; these endpoints set Accept: */* and send form bodies to avoid .json.
• Retry policy: cancel is idempotent and retries on 429/503 with exponential backoff; schedule and now do not auto-retry.
• Updates Smithy and openapi.json with /topics/{topicId}/bubble_up and /topics/{topicId}/bubble_up_now, regenerates the client, adds conformance tests (including form-body assertions). No breaking changes to existing bulk Bubble Up APIs.

^{Written for commit d382685. Summary will update on new commits.}

spec/hey.smithy:2591

• BubbleUpTopicNow is also declared non-idempotent, so the generated Go method bypasses doWithRetry and never retries a 429/503 despite this trait and the PR summary saying all three operations retry. Decide whether repeating “bubble up now” is safe; if it is, mark it idempotent and add a retry conformance case, otherwise remove/correct the advertised retry policy.

@heyRetry(maxAttempts: 2, baseDelayMs: 1000, backoff: "exponential", retryOn: [429, 503])
