Database performance tuning

See original GitHub issue

Subject of the issue

Database queries are not optimized.

There are a lot of queries which are jst select * on table… they need some sort of server side pagenation
some of them do ORDER BY dateadded DESC… i cldnt see indexes on the dateadded… so we cld change them to do order by id desc or create index on dateadded desc
https://keralarescue.in/contactus/?district=<district> for eg is mostly static. Introduce a redis/in memory cache and cache the result of the query for lets say 5 mins (edited) potentially cache generated content/query result on most of these pages which are almost static
explain analyze any complicated queries which exist, and build custom indexes to handle them

db is on AWS. I believe @biswaz and @cibingeorge are taking care of it.

Lets keep this thread clean as this is taken care of.
