2 nextjs scaffold with store mode shop and admin session experiment wiring event emission v1 (#17)

* chore: cleaning gitignore * formating and env documentation * feat: context switching of hotel/airline depndent on env var via middleware * fixed alignment and building * wrong file * prods * fixed applying style * better session cookie management * tentative session storage with maybe using airtable * migrated api of ingestion * events and products apge * fixing build * 13 create outline for research paper draft (#18) * updated outline for paper from issue * extra paper sections and some formalization of series data * algorithms and acknowledgements * updated outline for paper from issue * upadted text formating * event unification * refactor tracking to ues callbacks instead of refs * implement a pricing display api with session passing * moved middleware to proxy according to new changes in Nextjs * refactoed kafka ingestion to go via backend not web-db * Refactor docker-compose services to use individual Dockerfiles (#20) * Initial plan * Refactor services into individual Dockerfiles Co-authored-by: velocitatem <60182044+velocitatem@users.noreply.github.com> * Add EXPOSE directives to all Dockerfiles with port documentation Co-authored-by: velocitatem <60182044+velocitatem@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: velocitatem <60182044+velocitatem@users.noreply.github.com> * fixing small bugs and adding exepriments to tracking * added some doc
