Link FindStocks and FindComboPublications identifiers out

[Robbie1977]

The stock and publication reports rendered every identifier as dead text, so getting from a result to the stock centre or the paper meant copying a number into a search box.

FindStocks now emits three links, matching what FlyBase's own stock report offers: the FBst id resolves to its FlyBase report, the stock number resolves to the centre's own catalogue entry, and the collection name resolves to the centre's homepage. FindComboPublications gets the same treatment for the FBrf, DOI, PMID and PMCID. Genotype, title and citation stay plain text — FlyBase notation is full of brackets and must not be parsed as markdown.

The centre URLs come from chado's stockcollectionprop (homepage_url, order_url), read once per process, so the list cannot drift from FlyBase. Only Bloomington's per-stock pattern is hard-coded: its order_url is the batch-order cart, not a per-stock page. FlyORF's order_url is a per-line query prefix, so the stock number appends to it. The other five centres offer only a search box and FlyBase leaves their stock numbers unlinked too, so we do the same rather than invent URL patterns that would rot.

Parentheses are percent-encoded in link targets: MarkdownLinkComponent constrains the target to [^()[\]] so labels may contain brackets, and a DOI like 10.1002/(SICI)... would otherwise terminate the match early.

How to test

run_query?query_type=FindStocks&id=FBgn0020238
run_query?query_type=FindComboPublications&id=FBco0000052

Verified against chado for one stock per collection: BDSC and FlyORF stock numbers deep-link, the other five stay plain text, and all seven collections link to their homepage.

Follow-ups

• Cached FindStocks / FindComboPublications results need a force_refresh after release.
• The website side needs geppetto-vfb fix/stock-and-pub-linkouts to render an external target as a link rather than dead text.

Reopening from a slash-free branch: the Docker Image CI job tags the image with the branch name, and feat/flybase-stock-linkouts is not a valid Docker tag. Same commit, no content change.
