docs/update session summary through e3c979a

Add items 8-12 (timing log, account-change reset, optics
skip-if-in-position, OSA collision warning, tomo_alignment_scan) plus
the BEC_ptycho_align naming fix, updated test count (458), and
corresponding manual-check lines.

before this session — confirmed identical to flomni's, nothing changed
there. GUI needed no new UI code, just flipping lamni's
`has_zero_deg_reference` profile flag to `True`.
8. **`e59a42f`** — ported flomni's per-projection/tomogram JSONL timing log
(`~/data/raw/logs/timing_statistics/*.jsonl`) and `scilog_last_ptycho_scans(n)`
to lamni, adapted for lamni's own param names (no `fovx`/`fovy`/
`single_point_instead_of_fermat_scan` — uses `tomo_circfov`/
`lamni_piezo_range_x`/`y` instead).
9. **`b4c262d`** — lamni now offers a tomo-parameter reset when the active
BEC account changes (`_maybe_reset_params_on_account_change()`/
`_set_default_tomo_params()`), preventing a new experiment silently
inheriting the previous one's tuned FOV/stitch/etc.
10. **`7863b8f`** — `lfzp_in()`/`losa_in()` now skip the move (and, for the
FZP, the expensive feedback-disable + reset-enable cycle) when already in
position, matching flomni's `ffzp_in()`/`fosa_in()`. Also added the same
optimization to `losa_out()` as a lamni-side enhancement (flomni's
`fosa_out()` has no equivalent). **Found and fixed a real correctness
risk while checking every existing caller**: `x_ray_eye_align.py`'s
"Step 0: FZP centre" (start of a fresh alignment run) depended entirely
on `lfzp_in()`'s old *unconditional* reset to re-zero the interferometer
— now explicitly calls `lfzp_in(force_feedback_reset=True)` there so that
behavior is preserved regardless of the new skip-optimization.
11. **`db18929`** — added flomni's OSA collision-clearance warning
(`ffzp_info()`) to lamni's `lfzp_info()`. lamni's own collision-boundary
constant has never been measured, so it's read from `loptz`'s device
config (`userParameter.collision_offset`, currently unset everywhere,
including the simulated config) via a new non-raising
`_get_user_param_optional()` helper — prints a clear "not commissioned"
warning and skips the numeric estimate until someone adds the real
measured value to the config. Deliberately **not** a CLI-settable
parameter (per your explicit correction) — this is deployment-level
hardware calibration.
12. **`12b2538`, `e3c979a`** — new `lamni.tomo_alignment_scan()`, replacing
the awkward documented workaround (configure a full tomo_type-1 setup
with 96 projections, launch just `sub_tomo_scan(1, 0)`) with a dedicated
command mirroring flomni's: adjust `tomo_parameters()`, then call
`tomo_alignment_scan()` directly — no tomo_type/sub-tomogram bookkeeping
needed. Runs 12 points across the full 360° (lamni has no 180° symmetry
the way flomni does, so covers the whole circle rather than flomni's
5-point/180° scan). Aborts if x-ray-eye alignment hasn't been done yet.
Writes the same 4-line scan-number/angle/offset log flomni's version
does, to `~/data/raw/logs/ptychotomoalign_scannum.txt`, for
**`BEC_ptycho_align`** (not `SPEC_ptycho_align.m` as initially assumed —
corrected in `e3c979a`). `docs/user/ptychography/lamni.md`'s "Fine
alignment" section rewritten to match. Known scope limit: calls
`leye_out()` unconditionally (flomni's equivalent skip-if-already-set-up
optimization has no lamni-side helpers to reuse yet — separate follow-up
if needed).
**Parked, not done:** `DataDrivenLamNI`'s broken `_start_beam_check()` calls
(missing mixin) — deferred on request, separate task if ever needed.

real Matlab tool hasn't been confirmed against real data).
