fix(#48): add the missing version-local migration for syb_session

Adding SYBSession to migrations.Migrate was not enough. Schema reaches an
existing database only through a version-local file; with the previous
version already recorded in sys_migration, Migrate never re-ran and the
table simply never appeared. The unit tests build a fresh database every
time, so they stayed green while the real database was missing a table —
which surfaced as "Error 1146: Table 'goauto.syb_session' doesn't exist"
on the first import attempt.

server/.gitignore was hiding these files. go-admin ignores version-local
because it is where generated local migrations land, but every GoAuto
migration belongs in version control; the existing ones had been forced
in with `git add -f`. Un-ignoring *.go there also recovers four migrations
that were never committed at all — 1786700000000 through 1786700300000,
covering the base schema, device registration, heartbeat and collection
execution. A fresh clone could not have built a working database.

Guard the class of mistake rather than just this instance:

  - migrations.VerifyTables checks every model's table after migrating and
    names what is missing along with the fix.
  - The migrate command runs it, so the failure lands at migrate time
    instead of at the first request that needs the table.
  - initDB no longer discards migrateModel's error. Upstream had
    `_ = migrateModel()` followed by an unconditional "初始化成功", so a
    failed migration reported success and the launcher believed it.

Also records the two-step rule in Common-Changes: a new model needs both
the model registration and a new version file.
