…r schemas with nested types (apache#2307)

## Which issue does this PR close?

- Closes apache#2306.
- Downstream issue:
apache/datafusion-comet#3860

## What changes are included in this PR?

`build_fallback_field_id_map` iterated over Parquet leaf columns instead
of top-level fields when building the field ID to column index mapping
for migrated files (no embedded field IDs). When nested types (struct,
list, map) precede a primitive column, they expand into multiple leaves,
causing the mapping to diverge from
`add_fallback_field_ids_to_arrow_schema` which correctly assigns ordinal
IDs to top-level Arrow fields. This made predicates on columns after
nested types resolve to a leaf inside the group, crashing with "Leaf
column `id` in predicates isn't a root column in Parquet schema".

The fix iterates `root_schema().get_fields()` directly, assigning
ordinal IDs only to top-level fields. For non-primitive fields
(struct/list/map), it uses `get_column_root_idx` to advance past their
leaf columns. This mirrors iceberg-java's
`ParquetSchemaUtil.addFallbackIds()`, which iterates
`fileSchema.getFields()` assigning ordinal IDs to top-level fields.

Also renames "Leave column" to "Leaf column" in error messages.

## Are these changes tested?

- An integration test
(`test_predicate_on_migrated_file_with_nested_types`) writes a Parquet
file without field IDs containing struct, list, and map columns before
an `id` column, then reads with a predicate on `id`. This reproduces the
exact crash before the fix. Test data is constructed with `serde_arrow`
for readability.

- [Apache DataFusion Comet](https://github.com/apache/datafusion-comet)
used the repro test in

[apache/datafusion-comet#3860](apache/datafusion-comet#3860)
and it passes with this change:

…e#2301)

## Which issue does this PR close?

- Closes apache#2299.
## What changes are included in this PR?
- Add `coerce_int96_timestamps()` to patch the Arrow schema before
reading, using arrow-rs's schema hint mechanism
(`ArrowReaderOptions::with_schema`) to read
INT96 columns at the resolution specified by the Iceberg table schema
- `timestamp`/`timestamptz` → microsecond,
`timestamp_ns`/`timestamptz_ns` → nanosecond, per the [Iceberg
spec](https://iceberg.apache.org/spec/#primitive-types)
- Falls back to microsecond when no field ID is available (matching
Iceberg Java's `TimestampInt96Reader` behavior)
- Applied after all three schema resolution branches (with field IDs,
name mapping, positional fallback) so the fix covers both native and
migrated tables
- Handles INT96 inside nested types (structs, lists, maps) via
`ArrowSchemaVisitor` traversal
- Visitor and tests live in a standalone `arrow/int96.rs` module to keep
`reader.rs` manageable
- Made `visit_schema` in `arrow/schema.rs` `pub(crate)` so the coercion
visitor can reuse the existing traversal

## Are these changes tested?

- `test_read_int96_timestamps_with_field_ids` — files with embedded
field IDs (branch 1)
- `test_read_int96_timestamps_without_field_ids` — migrated files
without field IDs (branches 2/3)
- `test_read_int96_timestamps_in_struct` — INT96 inside a struct field
- `test_read_int96_timestamps_in_list` — INT96 inside a list field
(3-level Parquet LIST encoding)
- `test_read_int96_timestamps_in_map` — INT96 as map values
- All tests use dates outside the i64 nanosecond range (~1677-2262) to
confirm the overflow is avoided

## Which issue does this PR close?

- Fix the audit check by updating `aws-lc-sys` and `rustls-webpki`.
- Avoid pulling both the legacy `rustls` / Hyper 0.14 stack and the
newer `default-https-client` stack through inherited AWS SDK defaults.
([AWS SDK
announcement](awslabs/aws-sdk-rust#1257))

## What changes are included in this PR?

- Bump to `aws-lc-sys>=0.39.0` and `rustls-webpki>=0.103.10` to pass
security audit.
- Disable inherited AWS SDK default features for `aws-sdk-glue` and
`aws-sdk-s3tables`
- Explicitly enable `default-https-client` and `rt-tokio`
- Bump the minimum `aws-sdk-glue` version to `1.85`, the first version
that provides `default-https-client`

…python (apache#2278)

Addresses the security advisory GHSA-pwjx-qhcg-rvj4 for rustls-webpki <
0.103.10 in the Python bindings lockfile.

This is a rebase of apache#2268 onto main which already includes the root
Cargo.lock audit fix from apache#2274 (aws-lc-sys >= 0.39.0).

## What changes are included in this PR?
Relates to apache/iceberg#15742

This PR
- Add "ASF allowlist check"
- Pin commit for codeql.yml (zizmor recommended)
- Add back Github Action auto-update for dependabot (reverts apache#2267)
- Add cooldown to dependabot (zizmor recommended)
- `Swatinem/rust-cache@v2` -> `swatinem/rust-cache@v2` (fix case
sensitivity) [asf infra allowlist uses
lowercase](https://github.com/apache/infrastructure-actions/blob/fae466bc0d9821859a623cbc7648c750ff359ec6/approved_patterns.yml#L271)

We can add back dependabot for github action because the "ASF allowlist
check" will now alert when an action is not allowed (failures will no
longer be silent)
