* Fix the stack-overflow issue in AclOrch::getTableById()

In case the table_id and m_mirrorTableId/m_mirrorTableId are empty
The function would be called recursively without ending.

```
If we have some rule that does not have table defined, it will trigger this issue.

…sue. (sonic-net#22342)

Fix TACACS config revert to old config when device reboot issue.

#### Why I did it
Fix following bug:

1. When SONiC OS upgrade, old TACACS config will save to /etc/sonic/old_config/tacacs.json
2. After device reboot, TACACS config service (https://github.com/sonic-net/sonic-buildimage/blob/master/files/build_templates/tacacs-config.service) will restore TACACS config from /etc/sonic/old_config/tacacs.json, but this file will keep no change after restore TACACS config.
3. If TACACS service changed by user, because of #2, if device reboot again, the TACACS config been reverted back to old config in /etc/sonic/old_config/tacacs.json

Note: the TACACS config does not revert immediately after reboot, it will delay 5min 30sec:
https://github.com/sonic-net/sonic-buildimage/blob/master/files/build_templates/tacacs-config.timer

##### Work item tracking
- Microsoft ADO **(number only)**:32338799

#### How I did it
Move /etc/sonic/old_config/tacacs.json to /etc/sonic/old_config/tacacs.json_backup

#### How to verify it
Pass all test case.
Manually verify with following steps:

admin@vlab-01:~$ show tacacs
TACPLUS global auth_type login
TACPLUS global timeout 5 (default)
TACPLUS global passkey testing123

TACPLUS_SERVER address 10.250.0.102
               priority 1
               tcp_port 49

admin@vlab-01:~$ echo '
> {
>     "TACPLUS": {"global": { "auth_type": "login", "passkey": "12345" } }
> }' > /etc/sonic/old_config/tacacs.json
admin@vlab-01:~$ cat /etc/sonic/old_config/tacacs.json

{
    "TACPLUS": {"global": { "auth_type": "login", "passkey": "12345" } }
}

// then reboot device and wait for 6 minutes, because the TACACS config service will delay 5min 30sec after reboot:
https://github.com/sonic-net/sonic-buildimage/blob/master/files/build_templates/tacacs-config.timer

admin@vlab-01:~$ ls /etc/sonic/old_config/tacacs.json
ls: cannot access '/etc/sonic/old_config/tacacs.json': No such file or directory
admin@vlab-01:~$ show tacacs
TACPLUS global auth_type login
TACPLUS global timeout 5 (default)
TACPLUS global passkey 12345

TACPLUS_SERVER address 10.250.0.102
               priority 1
               tcp_port 49

#### Description for the changelog
Fix TACACS config revert to old config when device reboot issue.

…net#25643)

* [build] Add build timing report and dependency analysis tools

Add three scripts for build performance instrumentation:

- scripts/build-timing-report.sh: Parse per-package timing from build
  logs (HEADER/FOOTER timestamps), generate sorted duration table,
  phase breakdown, parallelism timeline, and CSV export.

- scripts/build-dep-graph.py: Parse rules/*.mk dependency graph,
  compute critical path, fan-out/fan-in bottleneck analysis, and
  generate DOT/JSON output for visualization.

- scripts/build-resource-monitor.sh: Sample CPU, memory, disk I/O,
  and Docker container count during builds for resource utilization
  analysis.

Add "make build-report" target to slave.mk that runs the timing
report and dependency analysis after a build completes.

Example output from a VS build on 24-core/30GB machine:
- 210 packages built in 53m wall time (173m CPU)
- Max concurrency: 5 (with SONIC_CONFIG_BUILD_JOBS=4)
- Critical path: 14 packages deep (libnl -> libswsscommon -> utilities)
- Top bottleneck: LIBSWSSCOMMON with 48 downstream dependents

* Address Copilot review: fix 17 bugs in build analysis scripts

- Use free -m with division instead of free -g to avoid rounding (#1)
- Add = and ?= to Makefile dependency regex patterns (#2, sonic-net#7)
- CPU calculation now uses /proc/stat delta (two reads) (#3, sonic-net#14)
- Fix misleading 'critical path estimate' comment (#4)
- Fix parallelism timeline comment (60s not 10s) (sonic-net#5)
- Include after-relationship packages in fan stats (sonic-net#6)
- Guard disk I/O division by zero when INTERVAL<=1 (sonic-net#8)
- Remove unused elapsed_line variable (sonic-net#9)
- Remove redundant LIBSWSSCOMMON_DBG check (sonic-net#10)
- Remove active_make_jobs from CSV header comment (sonic-net#11)
- Wire up _RDEPENDS parsing to build reverse deps (sonic-net#12)
- Remove unnecessary 'if v' filter on rdeps JSON (sonic-net#13)
- Remove unused REPORT_FORMAT parameter (sonic-net#15)
- Add cycle detection to critical path algorithm (sonic-net#16)
- Add execute permission check for companion scripts (sonic-net#17)
