107294: ttl: show table name for jobs in SHOW SCHEDULES r=chrisseto a=chrisseto

Previously, `SHOW SCHEDULES` would only show a table's ID for row level TTL jobs. For the convenience of debugging, this commit upgrades the `label` column to contain the table's name instead of its ID.

Rather than performing table name resolution at query time, the job name is set at creation time and updated by the schema change during table renames. This minimizes the likelihood of `SHOW SCHEDULES` being rendered unusable when a cluster is in an unstable state.

Epic: CRDB-18322
Fixes: #93774

107316: sqlproxyccl: simplify NewSubStopper r=JeffSwenson a=JeffSwenson

The lock in NewSubStopper caused lock ordering warnings when run under deadlock detection. The justification given for the lock's existence is wrong. If a closer is added to an already stopped stopper, the closer is called immediately.

Release note: None
Part of: #106571

107941: storage: don't import `testing` for `DisableMetamorphicSimpleValueEncoding` r=erikgrinaker a=erikgrinaker

We shouldn't link `testing` in binaries.

107950: testutils: fix determinism in random predecessor history tests r=jayshrivastava a=renatolabs

Previously, the `rng` instance used by the tests was initialized once in the `var` block. That meant that every assertion that relied on that rng was order-dependent: running a single test in that file in isolation would lead to failed assertions.

This commit ensures that every test resets the rng before making any assertions, guaranteeing we get the same values regardless of execution order.

Epic: none

Release note: None
