fix(statistics): keep player stats tab visible without local index (#851)

* fix(statistics): keep player stats tab visible without local index

Show the tab always and explain that player statistics require the local
library index, with a link to library settings, instead of hiding the tab.

* docs(release): CHANGELOG and credits for player stats tab UX (PR #851)

* docs(credits): drop minor library index and player stats tab fixes

Per team policy, small UX fixes (PR #850, #851) stay in CHANGELOG only.
