fix(bitbucket-cloud): fix status key handling for build statuses

Bitbucket Cloud limits commit status keys to 40 characters and uses
them to identify build statuses. Generated a new key on each
CreateStatus call causing duplicate statuses instead of updating
existing ones.

Fix the 40-char truncation to safely handle short names, use 1-based
indexing for status keys, and persist the generated key as a
PipelineRun annotation (pipeline-run-status-key) so subsequent calls
reuse the same key. Move GetCheckName to provider.GetBBCloudStatusKey,
add Index field to matcher.Match for stable instance counts, and add
e2e test to verify build status reporting.
