Go 1.27 runs encoding/json on the v2 engine. echo's default serializer
calls json.NewEncoder(w).Encode, which builds each response in a single
buffer before writing it, and the v2 engine grows that buffer in small
steps. A 9.6 MB applications page allocated about 25 MiB per request.

Replace echo's JSONSerializer in NewRouter with one that streams each
response through json.MarshalWrite into a pooled 64 KiB bufio.Writer.
The encoder flushes every 4 KiB on its own, and writing a large
response to the connection in pieces that small made it slower than
before. DefaultOptionsV1 is the option set encoding/json itself uses,
so the bytes on the wire do not change.

9.6 MB applications page over loopback HTTP:

            time               allocated
  no gzip   14.4 ms -> 12.6 ms  25.1 MiB -> 51 KiB
  gzip      73.9 ms -> 71.6 ms  27.5 MiB -> 347 KiB

A status response is unchanged.

CoinGecko and Messari records carry no stablecoin tags, so the classifier
labels them 'Other'. Their higher source priority let that 'Other' beat
DeFiLlama's 'Stablecoin' for every coin CMC does not list, dropping those
coins from stablecoin totals. The merge now takes the highest-priority
concrete category and falls back to 'Other' only when no source has one.

With the mock data this restores 43 coins (USDTB, USDX, crvUSD, BOLD, ...)
and $4.43B of market cap to the stablecoin totals.
