i18n: two es/tl wording items raised in #720 review, for the native-speaker pass #738

Two translation-quality items raised by automated reviewers during #720 (PR #734). Both were deliberately NOT changed — see the reasoning — and are filed here for the Phase 1.5 native-speaker es/tl review.

1. tl — possible malformed verb in glossaryDiscountDef

A reviewer claims web/src/i18n/tl.ts glossaryDiscountDef contains ilinalagay where the correct form is inilalagay (i- + -in- infix + reduplication of lagay).

Marked SUSPECTED by the reviewer, which is honest: it is not a native speaker, and neither is the driver. AGENTS.md #688 records that mechanical Tagalog affixation checks were built for exactly this class and rejected on evidence — Tagalog affixation defeats substring and stem matching. This is also the #662 class: a lower-case i18n typo that shipped in tl because catalogParity compares key sets only.

Needs a native speaker to settle. Do not fix on a tool's say-so.

2. es — sobre vs por encima de for "above list"

CodeRabbit initially raised this as an internal inconsistency. It was refuted with evidence and the reviewer withdrew it: all five keys agree with each other — aboveList, glossaryAboveListTerm, listPriceHintAbove, listPriceHintAboveNoPct, and the help prose all use "Sobre el precio de lista". #688 is about a locale disagreeing with itself, which does not apply.

What remains is a genuine quality question: sobre el precio de lista can read as "about/on the list price" as well as "above" it, where por encima de is unambiguous. A judgement for a native speaker, not a defect.

Why neither was changed in #720

Both locales are machine-drafted (#182). Substituting one non-native guess for another is not an improvement, and #720 had no native speaker available. Recording the specific claims here means the native-speaker pass gets concrete strings to check rather than a general instruction to re-read three catalogs.
