Update all copyright notices in shell scripts from 2025 to 2026.
## Changes
- **Igor Pecovnik**: 2013-2025 → 2013-2026 (129 files)
- **Ricardo Pardini**: 2023-2025 → 2023-2026, 2020-2025 → 2020-2026 (5 files)
## Additional Improvements
Also updated the backtitle in `lib/functions/configuration/interactive.sh`:
- Changed title from "Armbian building script" to "Armbian Linux build framework"
- Removed docs link for cleaner display
- Uses dynamic year calculation with separate declaration (fixes shellcheck SC2155)
- `USE_TMPFS=no` disables usage of generic tmpfs mechanism (still possibly used for rootfs/image building, which is unrelated), for last-resort cases
- use better/more descriptive `temp_dir_id`'s for kernel build than `k` (now `kernel_dest_install_dir`) and `kd` (now `kernel_debs_temp_dir`)
- specific image/dtb/headers packaging already had decent names, same for other .deb's
- replace `mktemp -d` with `mktemp -d --tmpdir "${temp_dir_id}-XXXXX"` in `prepare_temp_dir_in_workdir_and_schedule_cleanup()`, so we know what's using what in tmpfs

- wait 10s for sync call; otherwise warn user to be patient
- wait_for_sync "reason for sync" everywhere
- add @TODO for /run/user/0 etc and XDG_RUNTIME_DIR in chroot
- introduce generic `prepare_tmpfs_for()`, which manages it's own cleanup/dir removal
- use it for `WORKDIR` (which is `TMPDIR`) and `LOGDIR`
- adapt previous cleanup handlers for those, so they delete their contents but not the dir itself (which might be mounted)
- also: make `ARMBIAN_LOG_CLI_ID` readonly together with other superglobals
- set `XDG_RUNTIME_DIR` & `XDG_RUNTIME_DIR` together with `TMPDIR`
- kernel-make.sh: pass `CCACHE_TEMPDIR` down to Kernel make (thanks @the-Going)
