Conflict in src/cache.rs was a trivial comment wording difference, resolved by keeping the grammatically-correct plural. Also fixed a real bug this merge chain exposed: Stellar-Insightss#54 and Stellar-Insightss#58 (both already merged to main) independently numbered their migrations 031 (031_create_network_metrics_timeseries.sql and 031_create_daily_stat_snapshots.sql). sqlx::migrate! requires unique version numbers per migration, so main was left in a broken state. Renumbered the latter to 034_create_daily_stat_snapshots.sql (the next free slot after 032/033) — no code or other migration references the old filename. Verified with cargo check (clean).

Closes #45
Adds
migrations/031_create_network_metrics_timeseries.sql, a wide dailytable (
network_daily_metrics) with one row per UTC calendar day coveringdaily active accounts, new accounts, transaction count, payment volume,
average/median fee, and active Soroban contract count.
This is the schema several other endpoint issues (#15-#19) query directly.
A wide table was chosen over narrow per-metric tables since the target
queries are "give me everything for date X / the last N days," which a
wide table serves with a single row read per day instead of a multi-table
join. An
is_completeflag distinguishes a fully-computed day from apartially-written one (see #2's partial-run handling), and a present-but-
zero row is distinguishable from a missing row for #15's "gaps should be
null, not zero" requirement.
