Apply repo-review rules PP306, PP307, PP308

PP306: Specifies strict config
`--strict-config` should be in `addopts = [...]`. This forces
an error if a config setting is misspelled.

PP307: Specifies strict markers
`--strict-markers` should be in `addopts = [...]`. This forces
all markers to be specified in config, avoiding misspellings.

PP308: Specifies useful pytest summary
An explicit summary flag like `-ra` should be in `addopts = [...]`
(print summary of all fails/errors).
