Adds a shared `[redis]` config section with a single `CONN_STR` key that acts as the default Redis connection for every redis-backed subsystem whose own connection string is empty: `[cache].HOST`, `[session].PROVIDER_CONFIG`, `[queue].CONN_STR` and `[global_lock].SERVICE_CONN_STR`. Precedence: per-subsystem value > shared `[redis].CONN_STR` > existing built-in defaults. Fully backward compatible: when `[redis]` is not set, every code path behaves exactly as before. Motivation: today an admin with one Redis instance has to repeat the same connection string in up to four places (five once WebSocket lands). Requested by @wxiaoguang in [this review discussion](https://github.com/go-gitea/gitea/pull/36965#discussion_r3613306976) as a prerequisite for #36965. This follows the pattern used by GitLab and Mastodon: one global Redis definition, per-subsystem overrides fall back to it. Since #12385 all identical connection strings already share one client via `nosql.Manager`, so pointing all subsystems at `[redis].CONN_STR` naturally converges onto a single shared connection pool. Covered by table-driven unit tests per subsystem (fallback applies, own value wins, absent `[redis]` = unchanged behavior). A config-cheat-sheet update for gitea/docs will follow once this is merged. --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: TheFox0x7 <thefox0x7@gmail.com>
