`concurrently` finishes as soon as one of the threads fails or all exit
cleanly, but we want all the threads to continue until all of them
terminate.

Social crawlers don't run the Elm app, so links pre-selecting a proposal
previously shared the generic tool card. The Python server now injects the
proposal title into the OG/Twitter meta tags when a valid proposalId is present.

- index.html: OG title/description/image become Jinja2 variables (generic defaults)
- /page route: resolve the proposal title from Koios (meta_json.body.title),
picking the network from the request's networkId param
- validate the bech32 gov_action id before any network call
- cache lookups in-memory (1h on success, 60s on failure) with a size cap
- short timeout + generic fallback so a slow/erroring Koios never blocks a crawler
