* chore: Replace lodash with es-toolkit
Migrate all direct lodash imports to es-toolkit/compat for a smaller,
faster, lodash-compatible utility library. Transitive lodash usage from
other packages remains unchanged.
* fix: Restore isPlainObject semantics in CanCan policy
The lodash migration aliased `isObject` to `lodash/isPlainObject` and
the codemod incorrectly mapped the local name to es-toolkit's `isObject`,
which also returns true for arrays and functions. This caused condition
objects in policy definitions to be skipped, breaking authorization
checks across the codebase.
* fix: Restore unicode-aware length counting in validators
es-toolkit/compat's size() returns string.length, while lodash's _.size()
counts unicode code points. Switch to [...value].length to preserve the
previous behavior so multi-byte characters like emoji count as one.
Adds missing stable dependencies (e.g. `t`, prop callbacks, store refs,
`setFocusedCommentId`) and removes unnecessary ones across hooks where the
fix is straightforward. For the two MobX-observed `.orderedData` deps in
`History.tsx`, keeps the original deps and silences the false positive
with `eslint-disable-next-line` so the memos still recompute when the
underlying observable arrays change.
