Change wording in chronometer

[yubiuser]

What does this PR aim to accomplish?:

Brought up on discourse: https://discourse.pi-hole.net/t/pi-hole-says-it-is-blocking-80-of-ads-but-isnt/57870/11?u=yubiuser

Chronometer talks about "Ads" but not all domains lead to ads. This PR simply changed three lines

"Ads today" => "Blocked %"
"Blocked" => "Last Blckd"
"Top Advert" => "Top Blckd"

I'm not 100% sold on the abbreviation of blocked to blckd - but I wont block (lol) this if anyone else wants to approve

[yubiuser]

I'm happy to take suggestions, but it should fit in the confined space.

How about the following - I prefer to have the word "block" in the description, and even if it has no tense that's still OK with me.

Last block
Top block

As for "Blocked %", the number presented has the percent symbol trailing, so I think this could be simply "Blocked"

Something to consider - in our API we also use "echo ">top-ads >quit" | nc localhost 4711" We should probably clean that up to match.

Everything will be better with v6 ;-)
