chore(dns): trim the resolver list and drop "min" from the table headers

Five entries leave `DNS_AVAILABILITY_SERVERS`: `Alternate DNS`, `Alternate DNS 2`,
`Quad9 (UN 2)`, `Level 3 (alt)`, `Level 3 2 (alt)`. The four Level 3 addresses stay
as one group — `209.244.0.4` carried the name "Level 3 2", so the table showed the
same operator twice; it is "Level 3" now and the group numbers its four endpoints
itself. 54 UDP rows become 49 and 125 servers become 120, so both count assertions
in `config.rs` move with them.

The three latency columns drop the word from their headers — `DoH min` → `DoH`, and
so on in all four languages: the cell holds a latency, so the word said nothing new,
and `DoH`/`DoT`/`UDP` are protocol tokens that stay Latin in every locale (rule 4).

`DNS_UDP_SERVERS` keeps its entries: that list feeds test 2 through
`probe/domains.rs`, and the removal was about the resolvers test 1 probes.

Verified: `cargo test --workspace` (188 + 64 + 2) and
`cargo clippy --workspace --all-targets` (0 warnings). A live run reports
`DoH: 37 | DoT: 34 | UDP: 49`, its header reads `Провайдер │ DoH │ DoT │ UDP │
Реальный UDP резолвер │ Подмена`, and the Level 3 rows are `Level 3`, `Level 3 #2`,
`Level 3 #3`, `Level 3 #4`.
